RE: heads?

Um..... I would not go with 205's on a 331... just my opinion. They are too big for a 331 street car. I personally would go with 185's and they would be perfect.

AFS's either way...

Trick-(you in to thinking they)-flow are decent heads for a budget build, but if you want to make horsepower, do it right the first time...

RE: heads?

The biggest advantage to the TW's is that the valves aren't inline so you can run more lift w/o the clearance necessary for the AFR's or other heads and the valves are bigger than the 165's--which are $300 more.

I agree that a 205 head is too much for a 331. Bigger isn't always better, same w/ cams....
