So I decided I would do a leak-down test. I know, the results might be different if the engine was hot and fully oiled, but I did it anyway.

Test psi was 100psi and I did test both at top stroke and bottom of each cylinder.

Results were:

Cyl 1 top - 90%, bottom - 92%
Cyl 2 top - 84%, bottom - 88%
Cyl 3 top - 84%, bottom - 80%
Cyl 4 top - 90%, bottom - 90%
Cyl 5 top - 82%, bottom - 80%
Cyl 6 top - 86%, bottom - 84%
Cyl 7 top - 96%, bottom - 94%
Cyl 8 top - 90%, bottom - 90%

Now this was a long sitting, dry engine. Given the results I am going to replace the valve guide seals and hope for the best. If you think I'm screwing up let me know.
