I would probably go with the late-model two-bolt. I prefer a roller valvetrain and I don't like retrofitting since it is really expensive. Additionally, that late-model block is a one-piece rear main seal which will be better than the old two-piece design.

You only need be concerned about using that 4-bolt block if you're going over 500 horesepower or running at sustained RPM, neither of which sound likely in your case.
