You should definately go for the GT40 P heads. They actually flow better than the GT40 iron heads. I know, it sounds weird, but there have been many flowbench tests done on these heads. The revised spark plug location makes the fuel burn much better and also creates a bit of a swirl in the chamber for fuel mixing. And besides, you can buy a set of GT40P's from me for $200 plus shipping. The GT40 iron heads are much more expensive. If you're interested in a set of the P heads, email me at mblack@ou.edu
