I have the 302 block bored 30 over with a flat top replacment pistons and the Ford E-303 cam. I want to run the AFR 185 heads and 1.6 roller rockers. Can i do this? Will i have clearance? What chamber head and walves? What kind of roller rockers?

185's will require flycutting for sure. 165's will probably flow enough for you unless you really start cranking up the boost. If you want big valves w/o flycutting, look at the TFS Twisted Wedge (2.02/1.60)
