Deck height
Readings are as follows, did them all twice cause it looked like the head surface is un-even front to back, do not know if this is typical or if I should be looking at one of my other heads.
Cyl #1 54
Cyl #2 57
Cyl # 3 57/58ish
Cyl # 4 58
Cyl # 5 58/59ish
Cyl # 6 58/59ish
I think I am going to check another head if I can get some valves to seal without a huge ordeal.
