37 Ford build--IE: old Header issues thread /37 Ford/5.0/GT40P heads

[bluestang67]

My GT 40 P heads just came back from machine shop today getting the mounting holes drilled for clearance for the 1/2 bolts on the 351 . I heard a rumor that the Mustang GT shortie headers will work on the GT 40 P heads .

Having a set of shorties I went to garage and set the heads on the engine and couple bolted the headers to the heads . This is going to work well and going in the 37 I believe it will be easier then trying it in the 31 .


The #2 and #4 cylinder are the only cylinders that will require a dimple in the headers . The passenger side will have no clearance issues at all . This will be saving me money on headers and the mini starter required by some headers .

Some pics of headers on the P heads .
