i got a set of heads last nite and they are stamped E5TE

wondering if any one can tell me anything about them and if i can use them on my stock 92 302 block????

2nd is i have the explorer gt40 intake and i need to know what size bolts i need for it. it had none in it when i got it.

can i use the bolts out of my stock intake when i take it off????

and i heard there are a few things i need to do when i change the intakes over can any one that has done this tell me what i need to do.

thanks guys all info will help. im shooting for next week to get this done.....

Thoes are truck heads from the mid 80s, everything i read you can use them but they are not very good.
60-63 cc nominal.
i copied this from a Truck forum....
If you are open to suggestions, don't use the e5 castings. They are horribly exhaust restrictive with large smog bumps in the exhaust ports. I'd look for a set of e7 castings. The bumps are much smaller, and the heads flow better. There are also a set of e6 castings (e6se) but apparently they have an unusual combustion chamber, and are difficult to work with.

I'm installing e7 heads myself. I spent too much time trying to remove the smog bumps on e5 heads.



as for the bolts they should be the same but i dont know about that.

Have you tried calling summit/jegs? I bet they could tell you which bolts you need.

7/16" head bolts

Save a few $'s up and find a set of gt40p heads....well worth a little extra money for your build.

im not out much on them if i dont use them i only paid 40 bucks for them.

i would like to have a set of gt40 heads but every time i find some they are allready gone by the time i call and check on them.


only reason for looking for new heads is i have 2 bolts striped out for the driver side exhaust. and dont really like the idea of heliecoil if thats spelled right. lol

Helicoil is not a bad thing. It is actually stronger than the original thread if installed correctly.

well as of now im just goin to go with a heliecoil i guess and use my stock heads. thanks for all the info guys.
