I did just that when I set the V record last summer. All was fine in the land of div 6.

We have been thru two stock teardowns at National Races in last four or five months....for us all they have done in piston/gasket height area was add gasket and piston deck heights together and if the total was greater than spec it was OK. I watched piston to top of deck and make sure the piston doesn,t rock and give a bad reading if they catch it on high side. Just my .02 worth

Another one of the unwritten rule changes. So, why have a gasket thickness dimension? Just put a deck height dimension.
