With the heads reworked a second time, I’m back to the single 1.0 mm cylinder base gasket and more measuring for deck height and compression ratio. Compression is low for this big bore kit. Deck height is high at average of 1.91. Looks like we’re back to removing the cylinders to try a different gasket configuration.
I did take the additional step of assembling the rockers and turning the engine over with clay on the pistons to be sure of clearance with the valves. No issues there.
