Your not gonna have an issure with piston to valve clearence.....those things will be at least .050 in the hole.....if you are gonna spray it you'll want the rings opened up a little more. Put the end gap in the middle of the stock specs and you'll be fine up to a 150 shot...any more than that any your gonna wanna open em up more but be warned you'll have blow-by when just cruising. Don't go cheap on the rods and bolts if you are spraying. Get too ARP bolts. Stock rods that have been prepped will be okay but don't go over a 150 shot or you'll be pushing your luck. Make sure you do your homework on fuel system requirments when using the laughing gas as well.....it's fun stuff but if you don't know what you are doing you'll destroy a motor real quick.
