Sigh... I'll try to set the record straight :rolleyes: I'm NOT against Pro Comp, and I like YOUR heads, and I think you got a GOOD deal. But if I found a nice set of used econo W2's for 850, I would rather have them than your pro comps, and I don't care what material they used to make 'em. Further more, I've NEVER EVER EVER EVER EVER put 800+ into a cast head, and I've done more heads than you'd care to count!!!!!
