2 Questions:

1. Does anyone know of somewhere that sells headers for GT40P heads on a 351W in a foxbody? All I can find are headers for GT40 (non P)or TFS head 351W, or fro a 302.

2. Do GT40P heads require a special lower intake (i.e. different intake port shape or something)? Or will any 351W lower work?

reason I'm asking is I picked up a pair of used GT40P heads for $100 and was planning on putting them on my 302, but just came across a 351 for fairly cheap and wondering if I can use the 351 and the heads or if I should sell the heads to put towards the 351. Thanks for any input!

you'll have to use the ford racing shorties or mac has a knock off thats identical. i went with the mac due to cost.

a stock lower 5.0 intake will match up fine

Mac makes a GT40P specific header. I have the same set up on my truck. 351W, GT40P heads, Mac ceramic coated shorty headers, crane energizerroller rockers.
