I can't say about the oil pump.

since vortec heads transfer over to the old block so I don't know why the old heads wouldn't crossover to the newer block. You will need an old style intake. Being prostreet I am assuming that you are looking for a higher proformance than the vortecs have to offer. Since the 99 model block should already be set up with a roller cam, I would recommend spending the cash on a new roller cam. Unless they are not allowed in your class.
