eng. compression

Does anyone out there know what the compression on a 2.25 with a 7:1 head?

I've done my reading dry and wet.
I'm not shure if it's a 7 or 8:1. I think it's a late 7:1.
The results:
#1: 135/160
#2: 135/150
#3: 123/165
#4: 137/ 160

Is there someone who can comment on my results?

There should be an 8 stamped on the head if its 8-1. It appears that two things are going on. The first is a possible head gasket failure between the cylinder ( # 3 is quite a bit lower than the rest) and two, the rings are failing, thats why your compression jumps up so much during the wet test. I do believe.

You may have an inconsistency but those #'s seem pretty good for a 40 yr old engine.
