so these heads are on 87 and later 5.0 and 5.8, but not crown vic's or marquis. are they on trucks? is there any way to tell them apart if they are on the engine in a wrecking yard?
any idea what comp ratio they are. I think I am aiming for 9 or 9.5. I want to get the most out of this while still using pump gas.
They all look the same on the outside all the 5.0 HO s had them so did the trucks as far as I know. Some on the 351s only had some cracking issues.
The combustion chamber volume is the same on all E7s. Dont remember what off the top of my head.

You can tell the difference by the Air injection bump in the exhaust port. If you compare the Pre-E7 heads to the E7's themselves the Bump is much bigger in the pre-E7's.
I believe the combustion chamber size is 64cc's on the E7's and 69cc's from the D8's to the E6's.
