Everyone, I was over my friends house the other day bull****tin. And we were talking about investing in a porting and polishing kit. I have e7's layin around from a wrecked 80's mustang i had so i can practice on those heads. But i was thinking can the stock e7's ported and polished compare to any other street head's like gt-40's and such. Man i'd like to save money, maybe do the intake to and invest in a blower or put it on steroids
check out thumpers heads. you should be able to google his product "thumpers e7 heads" should work. he makes a set of ported e7 heads that perform very well. so to answer your question, yes e7 heads worked can perform as well as some aftermarket heads.
