1.6 rockers with stock 318 cam??

Not much bowl work as we got another, untouched port, at 50.7 @ .100", 108.9 @ .200" 160.5 @ .300", 171.6 @ .400 and 171.6 @ .500".

The flows for the slightly worked port were, 69.7 @ .100", 117.7 @ .200", 155.8 @ .300" 168.7 @ .400 and 169.9 @ .500". Valve job but nothing fancy.

The nice port from 2 years ago, with a roughed in valve job on the 318 head, shows what a 675 head can really do.

79.6 @ .100"
138.1 @ .200"
188.8 @ .300"
230.0 @ .400"
266.0 @ .500"
270.8 @ .540".

Pretty sure there is even more flow available, but haven't had the inclination to test the head more.
