blown 392 valve spring presure

[remcolent]

What's the advised springpresure open and closed.
For a 392 with 6-71 @ 13 psi max boost. max rpm around 6000.

I have a PAW regrind cam with to high valve sping presure I will wear out the cam verry quickly I think.

Would it be a good option to replace the valves with titanium valves , a lot les weight so less spring presure requierd ?????.

Can roler lifters be used on a non roler cam and what prevents the lifters from turning in the lifter bore??

Thanks

Only PAW can tell you answer to number 1
titanium valves are no good for street use
no rollers on non roller cam, link bars or keyways keep them from turning
