im gonna have 150 shot nx and waass wondeerin if i should do stage 2 or 6 liter heads


absolute speed heads..........

 

Are you asking about stage 2 LS1 heads vs. stock LQ9 heads?

Or S2 LS1's vs. S2 LQ9's?



If you're considering ported LQ9's, then your debate should be more LS6 vs. LQ9 than LS1 vs. LQ9.

5.3, LS1, LS6, LQ9...all have their advantages. It depends on what exactly you want.
