I would say nothing higher than a 75 shot if your running stock internal. Or get some forged aluminum pistons and I'd say around 125 shot would be safe for your motor. Just be safe because you don't want your pistons to melt, go through the exhaust valve, then right out your tail pipe lol or kill your motor completely
