GT40P Heads...

I have a friend who is trying to use these heads on his 351w mustang, he was wondering what type of headers will work for him? Any help would be appreciated it. Thanks.

Header options are very limited with these heads. I have Mac unequal length and I am having problems with them burning up my wire boots. I had to dimple the headers and run 90degree angle plugs. I looked into header spark plugs but these heads require a different sparkplug than traditional heads. They only come in a box of 10 and they cost 150 bucks. I havent put my boots on yet but I think it'll be fine now. Ford Racing also makes a P header and there are some bbk long tubes that can be used.

i was having the issue with the headers melting my spark boots what i did is went to discount auto and bought boot protectors they are like 15 dollars for 4 so u would need 2 packs but they keep the boots clean and melt free

Thanks I'll let him know...

I told him about this Forum, so if he comes in here asking the same question sorry.

FYI, GT40 and P heads do flow better than stock 351 heads.
