there is a number in the chamber where the arrow points "GT25" and the stock spark plugs don't fit.

No promises, but I think what you got there is a set of old truck heads.

I can faintly see 3 verticial lines at the front near the bottom......Of my eyes arent playing tricks on me you have a set of GT-40's...Plus the ports look bigger than E7's

the 3 lines on the front is a sure sign of 40's if there were 4 lines they would be GT40P's..If you look in where the rockers are you will see GT40 in there somewhere I am positive

If I were to guess, I'd say GT40's, judging by the 3 verticle bars at the end. If so, they would also have "GT" cast below the spark plug hole near the end, by the head bolt. But I always thought the GT40's used the same plug as the E7's.

I see them all the time at the race track I have 4 or 5 friends who race Ford circle track stock cars and thay all have GT40's and say they make more power than the P heads...I am on a pit crew for a friend who races a chev and they will tell you the advantage that ford has because they (ford) can run those head's....Theese cars have to run a stock motor...well atleast pass tech when they win

Gt40 iron. The 3 lines in the front of the casting indicate this. 4 lines indicate GT40P heads

I dont know if the GT-40 "turbo-swirl" heads are the same or not. But they are...1.94" intake and 1.54" exhaust valve....160cc intake port and 53cc exhaust port.

Good eye Roland!!! The iron GT40 heads came with 1.84/1.54's and flow around 190/150. Huge improvement over the e7 @ 150/120.
