The port volume for a 305 head is no where near 170 cc's.
It is much closer to 150 cc's.
Your right Eric,,,,my goof. They flow very similiar to some 350 heads from 2500-5500 depending on differant factors.But the port volume for 416 heads is more than 150. But let him and others check with the "Head specialists" and they will see,,,I'll not argue the point anymore,thanks.
