btw, are the ET 215cc 11* heads even better than 215cc TFS and 205cc AFR and usually will make more power than TFS and AFR?
I really like ET heads but just cause there on a 11* doesnt make them better then the other two each one has strong points and weaker points. All 3 are good heads

maybe you are correct because to what i can remember that i was told that the GM LS7 12* heads are better and will flow more and make more power than the GM performance parts C5R 11* heads. i think because the C5R 11* heads are older design than the GM LS7 12* heads.
