To MSD or not

Hello everyone, was looking for some opinions. I picked up a new in box 8534 MSD pro billet non vacuum distributer for $100 . couldn't resist price. but need an ignion box and coil. was wondering if i could get away with putting gm hei module in and coil. or should i get summit box and coil,or just get a plug and play distributer and sell the msd . motor is a 318 magnum 30 over with airgap comp cam 210/220 512 lift also not sure if a distributer with vacuum advance might be better better with a vacuum advance
