OK , I was in the middle of doing a little porting on the heads . I am mainly just opening the exhaust side a little and getting rid of the bump inside. I did one side and when I flipped it over I noticed the exhaust bumps were different. As this caught my attention, I noticed the heads have different stamps on them. The drivers side has WCP triangulated in a circle and a large 3 over one of the intake ports, a ford emblem in the middle and the number 25 stamped on the outside of the valve cover area. The passenger side has a CP in the same place as the WCP, a ford emblem where the Big #3 is and a big "T" in between the springs and in another spot. It is blank in the middle and it has the number 14 stamped on the outside of the valve cover area. Does any one know what this means. I remember reading a while back that the "T" head was a stock 5.0 HO head .
anyways the markings inside the cam valley lead me to believe the driver's side is the matching one. I am mostly interested in if the valves are the same size and if the chamber size is the same.
Leave it to the police to fix things half-assed. I do have a few old E7TE heads laying around from my old 5.0 . So since they both have the same valve sizes and the E7's have a smaller combustion chamber, the E7's should be better performance.
Just until I can get the money for better heads or get thumper460 to port them for me.
