M8 Flow test
Testing Harley Milwaukee 8 M8 cylinder head ported by MCE Performance. This head peaked at 379 using stock valves! It's going to take a pretty big motor or some high RPM to be able to take advantage of the breathing capacity that these things offer. A point worth noting, the port no longer stalls out at higher lifts, it kept increasing. Whereas the stock port stalled at .500" lift. This is a healthy indication even though the cams won't actually go to those lifts (above .500" in most cases).
