Those heads look really good and if OOB they are flowing over 300 they work too! I bot a new set of eddys MRL worked over and he only got 280 out of them.

A Comp 292H flat hyd cam runs pretty good in a 10-1 stroker with enough head. It comes on around 2500. That is what I was running in the 416 before I switched to a solid roller and those new eddy's. Have not ran it yet with the new heads.
