I'd talk to myron watson and see how full his plate is and what he thinks of sdalvaging yours verse a transplant. When Jeff and I were in his shop last he was redoing a 73 engine for, I think, $2300?

Start by pulling all the plugs keeping track of which hole each came out of. Take a good pic of each plug so we can judge the condition and color of each. Disconnect the fuel line and coil wire before moving on to the compression check.
Screw your compression tester into the first hole and get someone to turn the motor over 3 to 4 turns and record the compression reading. Do exactly the same for each hole. Next, put a small amount of oil in each hole before screwing the compression tester in. Just a half dozen drops should be all you need. Repeat the compression test for each cyl doing this and record the readings. If the results go up considerably it is an indication of ring/cyl wear.
Put everything back together and start the motor. While the motor is still warming up take something like a playing card or business card and fold it in half. Hold the fold against the bottom edge if the tailpipe. Does the card pulse away from the tailpipe consistently or does it get sucked up into the pipe? If it gets pulled up into the pipe it is an indication of valve problems. Repeat the test once the motor warms up.
These simple tests will tell us a lot about the condition of your motor. Best results will be had if the motor is tuned up and the carb and valves are adjusted properly. Let us know what you find.
