What can i expect with these heads

Either way it is illegal in cali.
Is there any valid hp gains with long tubes over macs that are for real? On a stock cubed car , are the long tube going to make more hp and tq or just top end hp?

As I recall, the chambers finished off at 61cc. That will get your c/r close to 11.0:1. I would suggest running a stock thickness gasket. The factory mls gaskets would work well in this case.
Good luck.
