Looks like I am leaking in 3 of the intakes probably bent. I am using oversized SS and thinking about going to titanium and also replacing the valve springs. We are thinking valve float could have caused it especially after seeing strange behaviour at over 9500rpm on the dyno. Any recommendations on valves and valve springs other than the Ferrera valves and crower springs which I am using. Should I swittch to Ti valves for weight issues since we are pulling 10,000rpm. Or should I stick to Ferrera valves and the crowers, I remember reading a post a while back on valves and I think Earl or someone stocked the Ti's....TIA.

 

Give us a brief description of your setup. We stock and use Supertech Valvetrains in all our head and they work well at over 10K RPM.
But its all in choosing the right valvespring setup with the cam you are using and how high RPM you plan to take it to.
