This really is going to be something in the order of a stage 5 head by the time it is finsihed! He's opening out the ports so that they are the exact size of the 325 inlet, then sticking in the 325 bigger valves. Dbilas cam to go in and then the Magnex 6-branch manifold should compliment the zone chip. Would be nice to see at least 210bhp from this lot.
Here's a couple of pics
Dave getting stuck in with the air tool
Damn that 6 branch looks sexy
731 casting 320 head, bigger valve seats roughly cut for now, markings show where some bits of weld need dropping to sort out the water jacket, then a skim, valve seats cut, lapped in and in goes the Dbilas
I'll still see ya Dave when I get the bottle to try bike throttle bodies
but a 3.5 is probably easier Good work anyway fella
