really....why not?...i was able to do it on mine...definetly could get the valve to move to its limits ... i know its not as acurate as measureing when disassembled but it would give a good idea of the wear...

The valve is seated with ~100 lbs seat pressure.

I really don't see how that can be accurate or repeatable.

so how about doing me a favor then....just for grins....before you disassemble check the movement at the top of the stem of one exhaust valve...wont take but a couple of minutes....then with the spring off....and ffinally what you get with bore gauge measurement...

i would really appreciate it and we wont say its anything but a what the heck check
