they'll fit but u won't get the best power out of them.. something like the WCCH LS7 heads would work great

 

yer it was just a Q i dont wont to spend a **** load on heads then find i hade a oil burning pistonslaping bottom end as some over here say will happen and then dump it and go back to to OEM block and have heads that that wouldn't suite it
please give me a break down on the difference of STOCK ls7 heads to ls3 heads flow rate ,valve size port shape, CR ect

 

whats wrong with ls7 cnc heads?

 

probably nothing just want to know the difference

 

A member here I dont remember his user though ran 9.6@143mph with PUMP GAS 454ci LSX and L92/LS3 Heads so they work great with 454ci with the right cam/ intake and other stuff.

 

who is the member with the 454 and ls3 heads?
