Thanks for the reply Matt
The current cam is smallish I.630 E.630 268 270 @ 50 and ground on a spikey 106 Separation. Pulls very hard to 6000 rpm then its all done.
I've got a new spec. I think I'll try with the new heads. I.663 E.688 278 284 @ 50 on what should be a little broader power band 110 separation.
Matt new Heads are Brodix 12 with heavy port work 2.20 Intake valve 1.60 exhaust valves.
Stack injected, down nozzles and 16 to 1 comp.
