The intake port has'nt had the chamber deshrouded on the sides, so the low lift will only get better. Overall I'm happy with it for a 1.92" valve and that God awful rocker boss taking up 1/2 the intake runner.

The exhaust I'm not happy with at all.

It's either in the short turn, or just the still small runner/exit, So first order of business is to open it up a little more and see where that get's me. I will not quit until I see over 200 cfm.
