Default Ls3 heads for ls7

With the ever growing drop valve issue with many ls7 heads from every year, even reworked heads there are some builders putting reworked ls3 heads on ls7..Has anyone heard any reports on this and what would you lose from a performance point of view?..Thanks

Its an idiotic way to address the real problem here.


Its cheap to address AHP does LS7 heads for 1400.


Good LS3 head and intake will cost more then that and offer a huge decrease in power.

Agreed, I never said it was a good idea it's something some are doing. Ahp is doing the work on my z06 end of summer. Good company, good people.
