1973-914 2.0 compression issues., 914 2.0 rebuild suggestions Options

I’ve a 73-914 With a the original 2.0L Fuel Injection engine. Has about 75k miles. Set for about 10 years, brought back to life about 6 months ago. Checked compression and got readings of 90-95 psi across all 4 cylinders. Engine seams to run pretty good with that compression. Doesn’t seam to smoke any while driving but some bluish smoke when you first start it up. Pulls good up to redline. I was hoping to get the compression up to a range of 135-150 psi. Without spending a lot of money, what would you recommend to improve the compression? Valve job, new rings? Who would you recommend to do the work in the area? Estimated cost, Located in Oregon. Thanks

90-95 is low, but its probably a good sign that they are all there, sort of.

Just for giggles, when did you last adjust valves?

Make sure the engine is fully warmed up.
Throttle should be wide open.
do the test will all the plugs removed to stop compression in the other cylinders from showing up, and just run the test with the starter.

Each cylinder, test, note the results of the test, add a few drops of oil to the cylinder and run the test again, noting any change. But simply having your engine warm is going to bring your compression numbers up.
