I have milled Js over .070 with no problems, you will have to do the math and cut the intake side also, not a big deal with a good machinist, How far down are the pistons in the hole? That can be more of a issue

I'd port the J's and mill 'em. More airflow potential than the magnums. Unless you buy some R/T heads. Then I'd say S can the J's...

I will be pulling the heads this weekend to see how far down in the hole the pisons are. Any good machinists in south jersey/philly area?
