heads and intake

I have to assume that guy mentioned the AFR's because of the 72cc option. Only thing I can think of. But if you haven't bought pistons yet, no point in buying a head just because it has the option for a larger chamber. Either way, it's really not going to be a big difference between the two style heads when you're boosting.

And like fastback said. Get a good block first or you're asking for trouble.

The TW 170 has a shorter port than the AFR 165 so the cross section is larger on the TW head..........
