how far the the pistons sitting in the hole below deck or are they at "zero" deck ? how thick of a HG are you going with and what will be your final "quench" ? I'm thinking of decking the block accordingly if need be and having them .010"-.015" in the hole with a .030"-.041" thick HG (shooting for a .040"-.050" quench) . just in case I ever have to clean up the block again .
I don't know all of the details, I'm leaving it up to the engine builder. They should be putting it all together here pretty soon so I will know more then.
