Yes that does make sense. I am remembering something about the early 1.5 blocks with 11mm headbolts suffering from cracks around the bolt holes.
More progress: Chased/cleaned the bolt holes Cleaned up the block deck. I really like that super scraper. Cleaned up the piston tops and measured piston protrusion with a small stout straightedge and feeler gauges: #1 .026 #2 .016 #3 .034 #4 .032 #5 .034 #6 .032 What's up with outlier #2? No signs of valve collision on piston top. Looks like I go with 2-notch head gasket, here are the specs: mm (in) 0.81-0.90 (0.032-0.035) 2-notch 0.91-1.02 (0.036-0.040) 3-notch It had a 3-notch replacement gasket. I think repair shops commonly replaced head gaskets w/ 3-notch across the board. Easier to stock one gasket version, and no having to measure/ no chance for valve interference. The tradeoff is lower performance. Here are photos of the piston tops. Can anyone decipher the markings? P1020688.JPG P1020689.JPG
