guys I appreciate all the responses I will have to get a set of custom Pistons as my block is 40 over and I extremely appreciate the advice I just thought since I had it crank and rods it would be a little cheaper thanks for all the replies
I went the custom route. Compression height was 1.320 off the shelf Diamond Piston. Had the pin moved to 1.340 to prevent having to mill the deck a bunch. $60 charge for the full set of pistons. That's way cheaper than decking a block, and potentially having to deal with machining an intake manifold to fit correctly.
