Default 5.3 heads on 6.0

I blew the 5.3 so I plan to swap in a 6.0. If I get a LQ4, what kind of compression would I be looking at with 5.3 heads milled .020 ?? Is it even feasable (sp) to do this??

I know when you mill that head .010 and slap it on a 5.7 liter it will give you 10.5 to 1 comp. Not sure bout the 6.0, and another thing would be piston to valve clearance.

me and slim told you there's no way a chunk of piston came out the motor as big as the one you had and the rest of that piston didn't somehow find the head. let me know if you need latino's number
