You can get spring compressors that work on the car.

Yeah, there is a tool that works while the head is on the car. I'm not sure who makes it (snap-on maybe?). It just bolts to the head and has a bar running across to pry against.

Read this VFAQ
Especially the part about feeding string into the cylinders to prevent the valves from dropping into the cylinders.

Link was dead for me.


I am not sure if it will work with our style head but many companies, like Matco and SnapOn, make a tool to fill the chamber with compressed air. The air will keep the valves in place, but I am not sure if it will fit down in our head. You will need a good size compressor so that your air supply, not the band, doesn't run short.

Took me a minute becasue I didn't know what it was called. I didn't even think about it, but it actualy looks like just the hose end of a compression tester.

Here is the actual one that will work for our cars at the bottom of the page.

Or you could get a compression tester, great tool to have anyway, and just use the hose for this job. The first is a basic tester and the third is a fancy pants one.
