can it be done? the reason is i am going turbo and using stock cams, so i dont need new springs, ret., but i have some bent exsaust valves, so i was going to go oversized to help spool up the turbo.

Stainless steel is the way to go.

If you want to order a set at a decent price (much cheaper than Ferrea) go here:

Call or email Angelo. He's a good guy.

I'm about 99.9% sure you can do this, cause I'm almost certain I've seen this before, but when you call, ask him. There should be no size different in the retainers and keepers... which would mean that it would fit. (The only reason I can't answer with 100% certainty is because I haven't done it myself, or seen it with my own eyes.)
