gday peoples.1975 ford p5 ltd. engine code T. now from what i know the T stood for two different things. either a four barrel carb and manifold with 2v heads, or four barrel carb and 4v heads, how can you tell 2v from 4v heads without taking them off?

Hi mate the 4v's should have a 4 on the right front corner of the head, near the valve cover .

plus the intake ports are alot bigger the exhaust ports are d style ,valves are bigger but the 4 on the head is the easiest.Geo

I thought the early 4Vs were stamped with a 4 or a 4 and a dot, but later models were bare.

as was already said in the corner a 2 or 4 the dot has no meaning. in 74 ford started putting 2v valves in the 4v heads and by 75 4v Cleveland's were all but extinct. You most likely do not have 4v heads unless someone changed them. 351m and 400's didn't have the 2 or 4 on most. Allegedly there were no 4v 351m or 400's made.
