Heads
And becuase of this im doing research on heads and cams
and im away that 5.3L heads will bump up the compression which is GREAT for all motor
would would the pros and cons be of running 5.3L heads of 6.0L heads or even some good 5.7L heads?
they also seem to make better numbers on the flow bench over the 5.7s
if you want to boost compression...don't see why you'd even consider 6Ls
