GT40P's are just explorer heads i think
GT40X's are better than the p's
GT40Z's are better than X's

GT-40Ps outflow 40s a nice bit, however you do need special headers I believe, although I'm not 100% sure on this. The aluminum GT-40X303s outflow the Ps, but only marginally so.

Depends on the condition. I paid $300 for my GT40Ps, and $150 for an Explorer upper and lower intake. $550 might be a little on the high side?. Several sets on ebay, also look here and in the Corral Classifieds
