Easiest/Cheapest way to a 4bbl 318?

Take the new set of heads to the local machine shop and have them cut .030 thousands and and about .036 on the intake side of the heads.
Just tell the machine shop you want .030 off the heads and they will measure and cut the intake side however much they need to.

Ok, forgive my ignorance again here, but when you say to take .030 off the head, are you talking about removing that much material off the "bottom" of the head where it mates to the block? If so, wouldn't this screw up how the intake aligns with the heads?

And I'm guessing the point of this would be to increase the compression ratio?
