Yep, another help identify my cyl heads....please!
I bought a project car......the engine was tore down already, awaiting a Trick Flow transplant on top. I need to know if these are 1986 heads or are the newer heads. What markings will tell me? and where are they?
Thanks in advance!!

Those heads aren't worth your time.

They are worse than the E7's in terms of flow.

So these are the 86 heads then?? Is that an E6 or E8 on the casting? Is this the area that tells you what they are? I assume that form 87 and up, they are E7??


Thanks

send those heads to the scrap bin or send them to me. Those are 86 E6 heads. Go out and get at least E7s or better yet Exploder GT40 heads and intake

Your asking us if that says e6 or e8, your the one who can put a magnifying glass up to it, we can only see the pic, but it's e6, those heads are one of the worst ever made. Throw them away.

I guess I think it looks like an E8, but is that possible? I assume the E7 combustion chamber looks different than the E6????


"IF" these were the E7 or Explorer heads, what stampings would be on them and where are they located?

Thanks

No there is no e8. If they were e7's it would say e7te instead of e6se. If they were explorer heads it would say gt40p under the valve cover. It doesnt seem like you want to believe they are e6's lol, you can pretend they are gt40's if you want, but you really got junk heads there.

Gt40p heads would have 4 vertical bars in the front and rear of the heads, and GT40 heads would have 3 bars in the front and rear of the heads apart from having gt/gtp and gt40/gt40p marked in different places..

Not really. All I want to know is how you tell the difference between the two and if E7 where for all the years after the E6 or was E7 the start of the newer head and they changed the E7 to E8...E9.... I didn't know. That's why I asked.
It would be nice if they were the E7's, but no big deal. I got the TF stuff with the car. My daughters 86 could have used the E7's...

Thanks for all the replies! Just trying to learn here....
