I'm going to go with a set of ported E7s soon. I'm thinking of having them milled .030" to add some extra compression and some extra HP...
I'm told i'll have to shim up my rockers the same amount that I milled the heads.
My question... since I have cut the heads down do I now have to modify [mill, plane whatever...] the lower intake to match the newly cut heads? Or does that not change at all? and wether the heads are untouched stock.. milled .030"... etc., lower intake will bolt up just fine?
Thanks.
