That was me who had the work done. With the exception of my Barracuda, all my other 65s were originally slant equipped. So I think I might go with with the slant in definitely 1 and maybe 2 of them (have 2 Offy valve covers). I wanted the Offy valve cover to look basically like a stock cover. So I got some sheet aluminum from Lowes and fabbed up the baffles based upon a stock valve cover and formed the stovepipe for the PCV valve. Instead of using the painted oil fill and PCV cap, I'll be using the chrome ones as seen on the Commando motors. The new one is at Leanna's right now for some extra work on the fins.
