Not looking for valve to head clearance,,,,,, I just set a late corvette LS-7 head on a6.0 block, and the exhaust valve 'kisses' the cylinder wall. I know I can use off-set dowels to slide down a bit, a smaller exhaust valve, bore the block, or even cut a relief in the bore, like they used to do on the big block chevys. I'm just not sure what the recommended valve to cylinder wall clearance should be?
Thanks, RICK
