Sorry about the mix up. I was looking for the demension of open valve to top of piston valve pocket in high dome piston. I am worried that with shaved heads of .030 my valves may actually hit the piston valve cut out. I need to know what the clearance is between the valve and the piston so I can adjust or make sure this does not happen. the only people that may have this info is someone with a shovelhead blue print. This has me pretty worried and I cannot find any info. if anyone has any information it would be great. thanks for the help Mark but it was not the info I was looking for.
