I searched and I couldnt find what I was looking for. What heads came on the 302 from a 95 f150. were they e6 heads?

 

No they will be the E7TE.

 

do you happen to know the difference between them?

 

The E6 heads have a deep kidney bean shaped combustion chamber with the valves sunk back and heavily shrowded, while the E7's have a D shaped chamber with the valves clear for the most part. The E6 heads were further choked with a massive air injection hump in the exhaust port. The E6 heads were installed on low output car 5.0 motors in the late '80s and early '90 and the '86 Stang 5.0. There are reports of them showing up in some truck 5.0's as well but this is rare.

Here's a pic of the E6 and E5 heads side by side, the E5's are identical to the E7 heads.

 

Thanks with the info, Now i dont feel so regretful for installing them on my build. Looking at your sig, how do you like your cam?

 

What heads did you use the E6 or E7?

 

I used E7,

 

OK good they're a much better head, the E6's need a bunch of work just to perform as well as the E7.

 

do u happen to have any pics of your headers? i know when i did mine on my 86 i ran into troubles with the cross member. i want some ideas for when i do this truck.

 

Yeah I have lots of pics here... http://www.flickr.com/photos/motorst...7602458567072/

I had clrearance trouble around the crossmember with the headers I installed last year but no problem at all with the headers I had before. The crazy thing is they were the same headers.. both Flowtech longtubes, the early headers were a much better design and didn't hang as low so clearance around the crossmember was no issue. I cut and welded these system from mendrel J bends in 2.5" tubing.

 

thats the same thing i had to do to my 85. looks like i will be doing it again since i will also be going flowtech. i can get them wholesale at $128 so i cant beat it

 

the e7s don't perform very well, hard to get them to support more than 350 horse

 

How much different are headers between a 302 and a 351w? The Long tube headers that I had on my 302 hung low, I wonder if I put them on my 351w, they would bu up a little closer to the floor pan
