Do you have any idea what the compression ratio is, or what pistons were used in the rebuild? Maybe measure the piston dish to give you a guesstimate of the CR.
Keep in mind that it's relatively easy to overcam a low compression engine and make it actually perform worse than with a smaller cam.

This^^^ compression will determine the cam (and head flow).
