I want to say 5 bolt flywheel setup.

You can likely have a machine shop back cut the pressure plate a bit. The 4G15 is not made to rev high with the 3V heads, so a little reduction will probably net a slightly better shift up high, and sacrifice some idle and decel/low speed stability. Might not be all that noticeable, as the flywheel weight might only drop less than 1lb.
