Has the changed? Check it all lines up with all the marks again, as it may have clipped the valves | |

Seems very low how long did you crank each cyclinder over for? For a 64k I'd expect higher unless head has valve damage, rings wouldn't wear out that fast and highly unlikely head gasket would go on all cyclinders at the same time | |

Ideally 140 and above, ultimately want them as close to each other across all 4 cyclinders. Do a dry test and then a wet test (poor cap full of oil in each cyclinder as you go and then test) and compare both dry and wet readings | |

Just had a look and lists no actual values, just states how to do the procedure and what certain drops in compression mean. | |

As long as they are roughly the same I wouldn't worry to much, I have a Haynes manual, i'll have a look later on | |
