What are the best valves and why? I hear Supertech, Manley, blah blah blah. Which is best per situation (maybe based on power/boost levels) and reason why? I'm sure many people would like to shine light on this topic. I sure would.

Im not 100% sure which ones are the best. I've had racers with 1000+whp saying both supertechs and both ferrera are best. Some said to get 6mm inconel exaust valves to withstand the heat.
I was going to say I have heard most the big brands are the best but i have never heard of a valve going bad only the valvesprings break or allow valves to float or the retainers break.
If the valves are seated perfect then valves should be fine. If they arent seated perfect, then eventually the valve can break
I think your incorrect lol jk. I've been watching some diy on making sure valves are flush with blue lap or lapping compound and go to work.Quote:

[MENTION=49]boosted_teg[/MENTION] this is what I was talking about with the lapping compound. I forget how long it is but the entire video is pretty good info.

What my boss sent me. "I like Fererra 6000 valves for there fit n finish. They are more than most. But I think there stronger."
