which heads...

i will be startin to build a 6.0 before to long and was wonderin what kind of heads i should go with. the motor will be stock 6.0 shortblock with upgraded rod bolts, bearing, etc...the cam i am probably gonna go with is either gonna be the thunderracing 230/224 .575/.563 111 LSA or the 236/230 .602/.575 112 LSA. Now what size heads should i look at doin? 5.3's, 5.7's or 6.0's. also which ever heads u recommend how does this setup sound to u?

yes, it will make a huge difference. oem lq4 shortblock will come with dished pistons (~8.6cc) and lq9 shortblocks will come with flat top pistons. to figure out your compression (i.e chamber size) well need to know which shortblock your using.
