Haven't had the Rocker Cover off yet Tim. but it had to be March or before because the engine casting number is March and the truck was delivered and registered in April of 1954.
Just thought it odd that it wasn't listed in any of the Chevrolet Parts books.
So what went wrong with the '54-'55 head that they came out with a revision?
