SBF FORD 260 289 302 347 351W WINDSOR TALL ALUMINUM FABRICATED VALVE COVERS
Semi polished/satin finish.
The welding is first class. The billet rails on these valve covers is approx. .25" 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.
This is a very good quality set of valve covers. Beware of others offering similar valve covers for a lower price. The quality is most likely inferior. Fit and finish are often compromised.
These valve covers have a somewhat satin semi polished finish. We find our customers prefer a finish that is somewhere between brushed and semi polished finish. We have sold thousands of these over the years, and all have been satisfied with the finish. These are considered a satin finish. We can honestly say they have a somewhat lower sheen than the picture shows. You will notice the strong reflections on the sides in the above pics, this is from flash glare.
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.
