What Should My Compression Be?

[SeventyMach1]

Stock heads still on there right now. I got 135-140 psi. (~965 kPa) on each cylinder. I thought this might be a little high..... but I don't have specs to look at. Thanks.

Sounds good, and it is good that they are all within 5psi.

It's fine, not high by far. Mine has around 170psi on all cylinders cold.
