were these ported by xfactorpitbulls? and do you have the actual flow sheet or the one he gave you just wondering because he sold me a set of heads that were susposted to flow 325+ when i got them flowed in town they were 296@6 i was not happy and when i pm him asking about it he ignored me so i would stay clear from brandon!

 

what cc are the heads, what valves in them

 

Got any pictures. Very interested. How many miles are on the springs and heads. Thanks

Do you know how much these would loweer om comp ratio?

 

They were actually VERY close to what he told me. I'm a student at The School of Automotive Machinists here in Houston, so I got to flow them on our bench. They were a tad lower than what he said, but it really wasn't significant at all. I told him and he was upset and offered to refund the money, but I was happy with them. This was a year ago.

 

The combustion chambers are at 70cc, the intake ports are 242cc, and the exhaust ports were at 80cc.

The valves are REV, stainless steel, 2.02" on the intake and 1.60" on the exhaust.

 

Springs are brand new, never run. Same with the valves. The heads haven't been installed since they were ported. Here are pics:









I don't know how much they will lower compression off the top of my head. I'll need more info about the engine it's going on (bore, stroke, piston dish/dome, headgasket, combustion chambers).

 

how much more do these heads flow than stock 02 ls1 heads?

 

Which flow #'s are posted above. The one's supplied when you bought them or the independent?

 

Those are the numbers I did myself.

 

bump for Friday!!

 

are you willing to sell the heads minus the springs

 

Yeah, sure.

 

whats the price with out springs??

 

x2......
