Cylinder head dyno shoot out

Earlie A said

But if by 'deshrouding' and creating the ideal shape for mid lift flow results in curve A, and intentionally leaving the chamber shrouded results in curve B, which one would you choose? I don't know the answer. That's one of the big reasons I'm spending so much time on these heads.

Have you tested A and B with an intake manifold on the head?

That would answer the questions right there.

My experience is A every time as long as the dip in the curve is the port and not the valve or the valve job or both.

Mike Jones and I discussed this on the phone at length in 2013.

It’s why I didn’t by a cam from him.

Put an intake on the head and test it. The best equalizer is a tunnel ram. A single plane is second best and a DP is the toughest to test with for stuff like this.

The different length runners and multiple curves can skew the results of the test.
