The standard is 145

The minimum is 92 (you read that right, 92!)

Please add this to the OP if possible, it'll probably save a lot of IX guys a heart attack.
Wow! Thank god I saw this. I thought that I was going to have to replace the motor when I saw 120 across the board. Lol!

Just did a compression test today. Car has stock block and stock head with the exception of 272 cams. None of the other mods I have would change the outcome.

Passenger to driver side. 160/165/160/165
