Around 100 psi, but what is very important is that the cylinder pressure are all close. A good rule of thumb is + - 5% is real good and I feel +- 10% is acceptable. So you are looking at 90 to 110 psi.

Do a search using "compression" and are a number of good posts at your fingertips.

Normal for those is 90 to 100.
