I've seen GENIII heads lift at 20+ psi (spike)... on 2 seperate occasions in 2 seperate street cars with F1R's... on 8.5:1 382/408 motors... both o-ringed... not that that matters... I think we're dealing with physics here.

At some point this is no longer about how much boost you can cram in... its about how much 4 bolts per cylinder can hold...

So if you happen to bang it off the rev limiter how are you going to keep the heads down?

You GENIII guys with 20+psi... how are you keeping your heads down? Street use apps please
