It is easiest to me just to pull the motor but that is a good bit of work. I would suggest getting the THICK 1 piece Felpro gasket, it is re-enforced adn will not leak. It's the best gasket I have found just ask for the THICK ONE.
I tne dto change anyhting while it is apart, like the Pilot Bearing, rear seal, just because it is too much work to take it all back out to change. If you take the oil pump down as cheap as they are, I would replace it get a nice Chrome-Moly pump shaft aslo.
