Nice replies,with ported heads there are a lot of choices better than the 210/224. The night I ran 11.42 Cody Kern ran 11.36 with CNC ported Lt4 heads. No doubt his ported head Lt1 would have run much faster with a bigger cam. I'm sticking with the stockhead route for now,with weight reduction i hope to run 11.20's at close to 118 with this cam and stockheads in the fall. Frank95z
