Well... sort of. The F150 didn't get a roller block until 95ish (IIRC), so with the OP's motor, yes. There is also some variance in combustion chamber volume (60-62cc's is the range I have read), but that ranges throughout all E7TE production, not just trucks.
And the 351 heads have a 1/2" bolt hole, and the 302 heads have a 7/16" bolt hole.
