I hear he is one of the best out there for porting.

And Predator-Z,

Do you know the size of the runners on Livernois Stage 3 heads?

IIRC 220cc

Brian tooley is one of the best over at TEA.

But not just sell the ls6 head and get TFS 215s!

Hey Predator, finally got that cam and it's at my engine guru's place being installed with an underdrive pulley on my C5.

Ambiant temps were my killer here and no meth is allowed in this country.
Mind you this was by no means a all out setup, but a reliable stock mannered combo.
It was still a 10.5 SCR, I only lost .5, but for $$ the power increase was well worth it.

That's cool I was just wonder how much tuning may have played in the new power with less compression. I was thinking you probably used something other than a .040 gasket and had a little less compression than 10.5. And yeah 60rwhp isn't bad for $800-$900.

actualy, It cost me less than that. like $500, tuning was just adjustment. Heads themselves probably gave ~25-30rwhp the rest was FI making use of the extra flow.

If you are referring the the PRC 243 heads, they are only a 225cc runner. I wouldn't exactly call that hogged out with a grinder.

Yeah, I was just figuring inthe Cometics, fluids and other odds and ends needed in a head swap.
