Are you running the stock caps in your motor? If not what type did you use, steel, aluminum or ductile iron?
Thanks for this information up bow


Thanks for the insight guys. I'm running the stock caps, ARP studs and a Hughes girdle.


Interestingly, the engine runs soooo much smoother throughout the RPM range with the new valve train parts and Mike at B3's geometry kit that it is astonishing.

I'm thinking that the harmonics that ate up my last valve train is what is missing from this build and likely why the motor feels like it runs so much smoother now. It's a night and day difference.
