I have done it in the past (25 + years ago) with the old steel shim gaskets that came with every gasket kit ever made - used some spray copper-tack on them. With- low compression (less than 11-1) it usually would work if the decks were flat - with stock bolts and a milled deck just make sure they don't bottom out - I would use the factory torque - maybe go up 5 lbs - but no more
