Mopar Performance 4532287 Cylinder Heads Stage VI Cast Iron?

I will check the casting numbers on the heads I have and the part numbers of the rocker arms, but I won't be able to until the weekend when I can dig them out. Mine were supposed to be the Stage V cast iron heads and were ported when new by Muscle Motors. I am pretty sure I had contact issues with 3/8" pushrods and regular big style Crane gold and Mopar blue aluminum rocker arms as well and had to run the offset rocker arms to clear the casting without more grinding on the heads.

Harland Sharp will make the rocker arms with the offset you need, but I don't know the cost. If you already have the heads with no damage and additional grinding for clearance is not an option, it is worth finding rocker arms, but know that these heads, in the end, will only perform similarly to an equally ported factory head.
