Gt40P headers???

[flyby84]

Going to buy some headers this week!! Will Flowtech shorties fit 40P heads? That is why I am still running stock headers and I just made up my mind to get a set.

 

[Cobra_Dusten]

mac P headers, and FRPP P headers are the only shorties that will fit

They will fit but you will not be able to reach the spark plugs with the headers on and the wires will probably be touching the headers, so technically they will fit but they wont work. Go with the single flange frpp P specific headers.

FRPP "P" headers were the best fitting headers I have ever used. I'd get those.

some long tubes work too, but mac p an fms are your choices in shorty.

I believe you can use any header you want....

"The header issues can be fixed with a shorter spark plug/ 45* angle boots/ or a small ding to clear.

Either heads are great!! Ported they are even better!!

Just me...........................

What is the shorter spark plug??

Idk thumper didn't mention it lol. Could always pm him to ask him....if people really want to know i'll do just that. I'm sure it's also in one of the other gtp head/ explorer motor posts though.

M-9430-P50 in a stainless header. M-9430-C50 and M-9430-P51 in Jet Hot.

Ford Racing Parts and Accessories at great prices has the stainless for $239 and the Jet Hot for $329.

I have read in many diferent threads on a few different forums that the BBK unequal length shorties also work very well.

I bought from Summit bacause they have them in stock, and M-9430-P50 is the part # for the above picture, im not 100% on this but i think M-9430-C50 doesnt fit the P heads, but i could be wrong

Last time i checked (and it's been a while) some of the shorty plugs costed 2-3 times as much.
Multiply that by 8, and consider you may change the plugs and in no time at all you land up not saving any money.
And if by chance the header burns your wire anyway, again now you need more plug wires.

IMO, just economize by buying the right headers.
