1978 318

I would think you would gain 1/2 a point of compression with the EQ heads and the felpro 1008 head gasket. Should get you to roughly 8.5:1 depending on how far in the hole the pistons are. With the whiplash cam, I think you should see a decent gain. My magnum 318 with a small 204/208 cam made 247 rwhp/265 rwtq. That is with a single plane mpi intake.
