A ton!!!

Seriously, it would lose about 1 full point give or take. Plus, it would be VERY detonation prone since there'd be no quench to speak of. So, you'd wind up with 5% less power, still have to run premium fuel/race gas and it would want to blow up at the slightest hint of bad fuel/incorrect timing.

Deck the block to keep piston to head clearance between .035"-.065" or get different pistons or rods would be my advice.
