My machine shop said that since the block has already been decked...and it's a little on the low side (about 0.005 outta the hole he said) decided to not deck it. While I was in the process of doing my cleaning and pre-assembly measurments I discovered that the deck is way to rough from a previous resurfacing to even dream of sealing against a head gasket...looks more like the surface of a file. It'll take about .007 or .008 to clean up, which will leave me about .013 or so out of the hole using calculated numbers. Actual measurements and rocking the piston in the bore yeilds about .0015-18 out of the hole.
With a .041 gasket, the quench is around .023"...which won't fly. With an .051 MLS gasket, this will set the quench at around .033 or so, which is a still a bit tight.
I was kicking around the idea of grabbing a 3rd gasket and using layers off of it to make a total thickness that would get my quench to .040 or slightly more.
This seems halfway hack to me though. What says the PB brain trust?
Option 2 is to find yet another block.
