Throughout the disassembly of the cylinder head on my 89 740 16v for valve replacement I had noticed that there was makrings on the valves... I'm kinda curious as to if this job has been done before, How would i identify if they are original?

the valves are marked as follows...

intake valve...

1317793 IN VOLVO IMP
T-T 4729/2

exhaust valve...

1317792 UT VOLVO IMP
TRWT 4730/2

I would think they would be at least dealer replacements if the job has been done before (looked like it may have been apart before).... There was also a lot of carbon build up on the intake valves, from what i gather this can be a common problem... I'll take a pic of them before i toss them out... and some pics of the torn down engine...
