Closed chambers gone bad… that’s a wrap

measure each piston at TDC with a bridge, you can even rock the piston while measuring. The older the build the bigger the rock. An uneven deck will get you in trouble as well. With those heavy pistons I would run a minimum .040 clearance to account for rod stretch at high rpm. I run a .060 thick gasket .020 above deck piston and spin to 6800 every pass.

Yes I’m thinking if i had at least a .060 I’d be in the clear, actually pulled both heads today and wiped down the pistons was just carbon. I have a nice deck bridge and just bought a good digital dial indicator so I’ll check and measure each piston. For the season I’m thinking I can get a proper head gasket that will give me .040 quench and I’ll run it and then send it out over winter for a stroker build. I’ll post up some photos later
