It's good to see the critics and the criticized go about this without things getting personal.
It's so not Yellow and/or ST of you (and Jeff and Dennis) and I for one appreciate it.
I don't recall any SB inline-valve head for any brand matching your high lift numbers. I'm looking forward to your on-track verification of these. I've never done any W8 or W9's, but always "heard" the W8's were better for a "big" application. Do you think you have enough material in critical places to just digitize and CNC it? One usually has to allow just a bit of cushion due to core shift.
And just wondering, if not another secret, have you modified your port for a longer valve?
No matter, good to see civilized dialog going on instead of chest beating.
