Decking a head .060" is not going to gain compression like decking a block .060" will. The last 76 440 I took apart had the pistons .156" in the hole. Shaving .060" off a head is going to do little to increase compression with a hole like that.
Everyone acts so worried that they will need to mill the intake if milling the block or heads. That is not an issue and is not needed. The only thing that might need done is the intake bolt holes might need a small amount of elongation. When you lower the deck or shave the heads what happens is this causes the intake to sit higher up on the heads. What's great about this is it allows the roof of the intake port to behigh ported to match the intake roof. Since the top of the intake port has a curve in it this allows you to straighten out the port roof on the heads. I have a simply little tool to get the angle on the intake port and the top of the head port in the same plane. While this might sound complicated to some it's actually very simple to do, and makes a big improvement in smooth air flow.
