I'm glad you and 72bluNblu mentioned this. I had no idea the KB 167 has a required ring gap. Didn't look for a spec or info sheet before I sent them to the machine shop for the the boring to be done. The The problem with decking the block and why I was asking, was the machine shop my block is at right now does not assemble anything and will not do the deck clearance measurements. I would have to get it back to my house, measure it and then send it back. I found another machine shop that will do the measurements and deck it, but that was just extra money and a day off work. Which I really did not want to do that to make sure I had days for The Nationals in August, and in case life happened and I needed days for whatever reason. I plan to measure the clearance when I get the block back to see where it is at then make a decision. If the clearances are close in both banks I may not mess with it being it will primarily be a street car and just use a thinner head gasket to make a little of the difference up.
