Default Head machining question

How much would you need to deck the 6.0 truck heads to have the same combustion chamber size as the ls2? and would it yield the same results power wise?


i hope this isnt a stupid question, im just trying to school myself in teh ls2/ls7

stock for stock the ls6/ls2 has similar low and midlift numbers as the lq4/lq9 but has better high lift cfm.

cool. would you say it would take a mild, moderate, or extensive porting job to mimic the highlift cfm? or would this sacrafice the mid/low lift cfm?

or is porting not the answer?
