It made me curious enough to finally cc an intake runner of a set of Edelbrock heads I ported years ago that have worked so well for me. My heads maxed out at 315-318 cfm with a 2.08 valve with a 192 cc runner. Thickflow advertises there’s as a 190 cc runner. Now did they leave enough meat to offer a 220-230 cc head down the road? My money is saying yes. Raise the roof some, push the rocker over some, and BINGO 330-340 cfm, maybe more with a 2.08 valve. Hmmmmm.
