They're Mustang, pickup and van heads. Cast in August 24th 1992. Could be off either a 302 or a 351, depending on the head bolt hole size.
E7- 87 T = Truck E= engine group there basicly H.O mustang heads 87-95 they were also used on truck and van engines,and lsc lincolns
thanks guys, if cheap enough; are they worth pickin up for a rebuild and port polish job to throw on my mild 73 302? are there differences between my factory 73 302 heads and these heads?
Yea, they're better designed for flow, but they need port work on the exhaust sides to get their full potential. I wouldn't pay more than $50 for the pair though. There's plenty enough made to pick from. They were in production for 10 years.
