Need some advice

Would milling 80k off get most /'s to a 9.0 to 1 Compression Charrlie_S ? Just thought I would ask while you are here :happy10: Thank you for your time :happy10:

Mike, impossible to say. Too much variation in actual manufacturing as compared to specs, and aftermarket head gasket thickness. Need to pull the head and take measuremnts, then you can determine how much to mill.
