A quick simple question Idk the anwser to and just wanna be sure. I plan on buying AFR heads I know 185 would be best for 302stock/331stroked which I plan on doing in the future but right now I just wanna bolt them on and just worry about that later. So could I buy the 165s and when I am ready to 331 it could I send them to TEA and pay them to turn them into 185s? And if so and you have done this do you know what the cost would be?
