I know a machinist I could take it to, I am just wondering. Thanks

Take a look at tristate cylinder head, got some gt40p from them awhile ago, got 1.94/1.54 valves, new springs, seats all ready to go.

Don't the GT-40P heads take special headers/exhaust manifolds? TO clear the special plugs?

Maybe that's just for installs in 66 F-100's. I remember reading it somewhere.

I am trying to get that answered on another thread here as well. I haven't gotten any replies from someone with direct experience yet though. I can handle some modifying, just as long as the cost doesn't offset a different type of head.

IIRC it's possible to use long tube headers with 90^ spark plug boots to avoid having to get the special headers for the P heads. If you use shorty headers you have to get the real expensive special ones. I'm pretty sure thats right but not 100%.
