stock valves ok for 400whp?
Building a LS for boost. Just wanted to know if my stock valves are ok for 400whp on pump gas.
upgrading to crower dual valve springs, crower steel retainers, and 402-t. Should i get valves too? im only gonna go for 400whp.
im asking because i dont wanna upgrade something that i dont need to. Its also gonna be my daily driver, if that matters.

OEM type-R valves are the best. Stock valves in general are good till A LOT of hp over 400whp. Tune it correctly and youll never have a problem.

ive never worried about valves and im looking to run over 400whp. and it does have alot to do with the tuning. ive never worried about tuning either cos im willing to shell out the cash to do everything right like most

If you are upgrading your valve springs upgrade your valves. Stock valves with aftermarket springs occationally fatigue due to higher seat pressure. I know 2 cases where this type of fatigue has happened. In both cases the motor was destroyed.
There is no point skipping $200 and risking your whole motor.
