Notice the high quality welding around the thick plate aluminum rail. Many fabricated valve covers on the market are not like this.

The welding is first class. The billet rails on these valve covers is approx. .225" thick. The aluminum sheet metal is approx. .075" thick. We know many on the market to be much thinner in these areas. This is why many other sellers fail to mention these specs.

As you can see in the picture below, these valve covers have a thick billet rail and an internal baffle.

You will have to remove the internal baffle when using stud girdles.

The pictures above and below show these valve covers on one of our engines. One is with flash, and the other is without the flash. They give the engine that true hard core race look. Flash glare was excessive.

THIS IS A SET OF TRUE ALUMINUM FABRICATED VALVE COVERS.

The quality is outstanding relative to the low cost. For those wanting a less shiny finish, a somewhat satin/brushed look, see our other listings for this same style valve cover, same part number with "SATIN" at the end of the part number. Many similar valve covers on the market lack the refinement these have. As mentioned earlier in the ad, these valve covers do not have a true mirror polished finish. They are a bright aluminum finish with a clear anodized coating to prevent discoloration/oxidation. You may notice upon close observation light striations in the finish, but when mounted on the engine these are hardly noticeable. Most of the so called polished valve covers on the market have a similar finish, and we have had very few complaints about this. If the valve covers had a true mirror polished finish on them, they would appear to be chrome plated, and that is what many people are trying to stay away from. Some customers prefer virtually no shine at all, and we have them with a satin aluminum finish in our other listings.

Part number 6145-POL

These valve covers are 3.25" tall on the inside, not including the valve cover gasket. Most vc gaskets on the market are approx. .175" thick, and this brings the total height to 3.425". There are extra thick gaskets available that will bring the height to approx. 3.550", and will certainly clear most any stud girdles and roller rockers on the market with ease. Our Gold Series stud girdles have oversized bars that are wider then most and these valve covers clear them with the use of the regular .175" thick vc gaskets, but the stud girdles are somewhat close to the opening in the top of the valve valve cover.

Our engine room has reported to us that using the extra thick gaskets not only seals around the rails much better than the regular ones, but that the additional thickness allows better clearance for the stud girdles and is of great benefit when adding oil to the engine. The stud girdles are usually very close to the opening in the valve covers when using the regular valve cover gaskets. The part number for the extra thick gaskets is 7483-ET.

If you have AFR heads, you must run the extra thick valve cover gaskets due to the outer rail design on these type heads. The AFR outer rail sits lower than many other heads on the market and this causes these valve covers to require the use of the extra thick gaskets to clear stud girdles.

You will have to remove the internal baffle in the valve covers when using stud girdles.

These valve covers are made from aluminum plate/sheet, not cast aluminum. They have a true billet aluminum rail, not folded over sheet aluminum as many do. There are many similar valve covers on the market, and some are inferior by comparison from what we have seen.

***********************************************************

Important Note.

We have used these valve covers on thousands of our high performance engines for over 10 years without any issues. On occasion, you may notice a slight degree of warpage on the rails before installation. This is due to the heat generated by the massive amount of welding done around the outer edge of the rails. This warpage is not a problem. When the valve covers are bolted on, they will pull down flat and seal well. Any micro amounts of variation left over after you have bolted them down will be compensated for by the gaskets. Any and all fabricated valve covers with such welding on the rails will have this characteristic. It's simply not a problem in the least. We dyno many of the engines using these valve covers. The engines are brought up to considerably high rpm levels, and rarely do we ever see any signs of oil seepage. They seal very well. The extra thick valve cover gaskets we use do an excellent job of sealing around the valve covers: Part number 7483-ET. See our other listings for these. Every engine we build uses the extra thick gaskets.

When we dyno a brand new engine, the crankcase pressure is higher than normal until the engine rings seat. This causes the oil to seep from any possible exit on the engine, such as around the valve covers and gaskets. We had always used our regular black neoprene gaskets on the engines but on occasion had to use the extra thick ones due to stud girdle clearance with certain heads. Our engine builders noticed that the extra thick valve cover gaskets had virtually zero seepage as compared the regular neoprene gaskets. As we see it, the extra thick gaskets are the key factor in eliminating seepage. Extra thick valve cover gaskets also give the engine a more pronounced (wide/tall) appearance.

 

The finish on these valve covers may on occasion have very minor cosmetic flaws on them. In the world of mass production, it's to be expected. The massive amount of welding on the rails can sometimes leave small spatter marks in some areas. You may also see very minor scratches in the finish. These flaws are only noticeable upon close observation. Once mounted on the engine, these very small cosmetic blemishes are not noticeable from a distance of several feet. In most cases, the valve covers are flawless or nearly flawless. There are some very high end fabricated valve covers on the market that cost four to five times as much, and on those you may even find minor flaws, but it's less likely due to their extreme cost. As mentioned above, you cannot see these minor flaws from the normal viewing distance standing in front of the car.

These valve covers will certainly clear most any stud-girdles and roller rockers on the market. Our Gold Series stud girdles have oversized bars that are wider than most and these valve covers do clear them with ease.

The rocker studs used in our engines are the ARP long version, as that is what is required for the huge/thick Comp High Energy rockers. Even when topped off with the oversized stud girdles, including the tall poly locks, there were no clearance issues for these valve covers when using the extra thick valve cover gaskets. We have used over 1500 sets of these or similar style valve covers on our sbc engines, and used as many 5 different popular styles of roller rockers and yet to have an interference issue. This is not to say you will never encounter some interference with certain rockers on the market, but the Comp High Energy rockers and the huge Scorpion race series have given no problems and they are far from small in size. It would be fair to say that there are few if any roller rockers or stud girdles on the market that will give you a problem with these valve covers.

The picture below is one of our engines with the large Comp High Energy rockers and our oversized stud girdles that will be topped off with a set of these style valve covers. Also notice that we have the stud girdles set high up on the on the poly locks and clearance is still not a problem. Our engines all use 200 long valves, with 1.46 diameter springs. This makes valve cover fit even more challenging. The valve cover gaskets we now use are thicker than normal.

Painting these valve covers are not a problem. We have painted them for many of our customers who have purchased an engine from us.
