Engine is done for this year. Found my puffing issue when I had the heads off checking for water sealing issues. Flycuts for the piston reliefs were cut too deep. Found a hole in #8 piston. I can only assume the rest of the pistons are ready to pop in the same spots. New pistons are not in the budget at this time so the engine will go back under wraps. Plenty of work left to do on the car itself, with plenty of parts floating around.
