72 340 AAWJ head questions

I have planed .060 off of some 587 72 340 heads. Planed the intake surface as well so an uncut intake would still bolt rite on. Cheap way to get a little more compression out of the engine w/o changing the stock (way in the hole) pistons. The compression was still only around 9.5:1 so I went with a .480 cam. Went pretty good when said and done. To compensate for the planed heads you can shim your rocker shafts, and/or run some adjustable rockers. I only went this route because it was a fresh short block. If I had built from scratch I would have bought some higher comp. pistons.
