drevil1,
Given that you're trying to use what you have and minimize further out of pocket expenses right not, the best advice, already mentioned, may be to rebuild those 62 heads. Compression will be right on for the RAIV cam.
IF money permits, I'm sure you'd be pleased with the results of a port job on them by someone like SD Performance. But that may be above budget.
Best of luck,
Stuart
