D5TE-EB cylinder heads
I believe you have these heads: 1975-77 351W, casting# D5TE-EB
60.4cc combustion chambers.
Valve sizes: 1.84″ 1.54″
Internal air ports (anti-pollution provision)
From another post: "...mid 70's t-birds with a 351W had similar castings to the 69/70 windsor castings. The ports/valves are the same, the only difference being the air injection ports and hardened valve seats. The casting # was D5TE."
Actually a difference will be that the 69/70 heads have eight intake manifold attaching bolts, whereas the D5TE will have six.
