Think of your IVC at 52 degrees. That's after BDC. In other words piston is on the way up. You want good fill? You need high port velocity to maintain airflow direction even though the piston is coming up.
Flow determines the max power the heads will support. Smallest port that makes that flow will always do the best.
You can call anyone you want. Nobody will disagree.

DUDES FOR THE Rich with Stock'ish head HP. Most of the power he's getting is compression Vs others Damn sure wasn't impressed with the 454 and 12.5 compression and 775 HP... TSP was only 25 HP off with a factory intake, less compression and a hydraulic roller

That is exactly the issue with large ports. They shine with rpm. It is easy to get hung up on flow, but more flow is not always better just like more cam is not always better.

Dude does good work and AFR are good heads ...I just don't think he or his products are the end all.. like what's done here. Other Builders don't post here made short... Cost to post and reason most the Greats are gone and never to be seen again. ED @ FTI has been getting ET's for Year's. Who you think came up with Ls1sales. That wasn't me.

Very little at all going on in the LS/hemi/coyote section to even speak of.
