Porting 351W heads
Intake and exhaust work together. You can just port the intake, but if exhaust flows poorly, cylinders will not evacuate and volumetric efficiency suffers. I have my engine apart and I plan to take some pics of the ports on my ported '70 351 heads that I wished I took before I put it together 3 years ago. I hope to post the pics soon.
