You do not have to worry about flycutting the pistons as long as you follow that simple rule. The E-303 cam has a duration of 220 degrees at .050 lift. So that cam is not a problem even with 1.7 rockers. I don't care what heads are on the engine that cam is not a problem.

I dont even think you can slap 185's on a stock block with the stock cam. When I was looking at heads I was told by Summit that I would have to flycut my pistons in order to use them.
