Does it matter where I get GT40 heads from?
I have a 1987 F150 4x4 with a 351W HO in it and I want to put on a set of GT40 heads. I called a couple of yards and they don't have the F3ZE-AA ones from a mustang but do have some from an explorer (E9TE6049AA) are these the same?

All in good fun, had the nickname since highschool. Thanks for the help. I want to put a set of these heads on my 351 W HO to help with air flow. When I do and order headers do I order them for the explorer or still with the F150 info?

Order heades for your truck not the Explorer, and adding 1.7 rockers would also help improve airflow a bit.

Will do, thanks.
I want to remove all smog/a.i.r. additions also, anything to watch out for concerning these? I saw on site that someone used 5/8th inch bolts to plug the holes at the rear of the heads (I didn't know they were tapped) and hopefully I can get a set of shorty headers without all the extra smog holes. I will order an edelbrock intake without the egr hookups (if I can) switch the heads (port & Polish ???), change the rockers like you suggested, add the headers and a new edelbrock performer 4 barrel carb. Anything else anyone can think of thats pretty much a bolt on application?
