Anyone ever heard of them? I'm looking at a set of heads that are new castings, and has all new qualcast street duty valves. Going an a 700 hp, 15#'s of boost LS motor. I've never heard of them so I'm leary. Anyone with experience with them?

If you have reservations, why go forward ? I will tell you what I tell lots of people, get off your wallet or gamble with the money you have.

I have used them in bone stock applications. Since you plan on making 700 HP, I would upgrade to a better valve.

after your last incident with the LS why even chance it ?? a good top of the line stainless valve isnt alot of money

Trying to negotiate a valve upgrade right now.
