Im trying to get the most power out of my ls2 so i plan on ordering a FAST intake ported T-Body and i wanna get AFR 205 heads but was wondering if i should leave them unported or not. What are the pros and cons on porting AFR heads? Thanks
Sinister, here is what Tony Mamo sent me when I broached the subject with him. He opens the chambers to fit a 4" bore and minor porting. It picks up about 2cc in the chamber so milling is recommeded unless the new compression ratio fits in your plans.
