Working on putting together a hemi for stock appearing. Head will have stock size valves (27/25) and will be unmilled, but with chamber welded to get compression up. With a +.020 rod on the stock crank and stock piston (zero deck) and .036” gasket, am I going to be running into a piston to valve clearance issue? If need be i can fly cut the piston but I would rather not if i can avoid it.
