PEP. PBm. manley . delwest have used Rev .howards extreme Black . others ... never lost a valve hope i never do
Pat, the Manley valve I used was new old stock. Not sure what the valves were in the heads I got. Based on what I saw of the springs and the way they were shimmed, the valve guide that was too long, keeper hit top of seal, I'm pretty sure this guy just got the cheapest stainless valves he could get, when I looked the pro comp were the cheapest. I put some Manley exhaust valves in, and replaced the springs with known ones, re shimmed and checked valve train geometry, I figured I'd trust the valves. It's a street motor, and I don't really rev it much anyway. And the way those heads were set up that valve may have been cracked when I got them. I looked em all over, but may have been damaged and didn't show. Most of whats in my engine is overkill. I probably could get by with a stock motor. I guess I'm just getting old........... I do remember dropping one on a really hot sbc in the traps.......ouch it didn't knock a hole in those pop ups but it made a mess of the piston head and gave the combustion chamber in those air flow research heads that freshly chewed look.....
