I am currently doing a 6.0L conversion in my 98 TA, I am using a stock 6.0L Iron block out of a 01 Silverado and am using stock LS1 heads [kind of on a budget. My question is, How much would I need to mill the 5.7 heads to reach 10.5:1 compression with the dished piston on the 6.0L block. I do not know the cc on the pistons but everything is stock, can someone please help me out??

 

you are better off finding LQ9 heads and mill those.
Not only does the 6.0 have a bigger bore, but the LS1 heads will flow less. LQ ( heads have the same runners as LS6)

 

LQ9 heads are what size engine, thanks.. i know i know damn newbies

 

LQ9/LQ4 are 6.0's, one is high compression, the other low compression. Seems like your block is LQ4 with dished pistons.

 

ok so the lq9 did not have dished pistons??? Now can anyone tell me the chamber volume on the pistons of the LQ4??
