My pistons are 0.054" below the deck and have valve notches in them so I'm not really worried about valve clearence.

In order for me to achieve my goal of 9.5:1 static compression I need to mill 0.065" off my 587 heads and I need to know if the heads themselves will have a problem with this.

I would love to do 302 heads, but these 587s only have about 1000 miles on them. Milling them will only cost about $150 compared to $500-600 to build a set of 302 heads. SO I'd like to go the more inexpensive route.

BTW, I'm also planning on using 0.028" gaskets along with the milling.
