larry has a great reputation, 330 with a 2.02 valve and that head still seems overly ambitious though.
My W5 heads, that later went 140 mph at 3220 pounds didnt break 300 on one bench, and another set ported by another guy didnt go 300 on a different bench either. Big swings obviously bench to bench
Would love to see that “330” head go down a track.
