The thing is, I live in Istanbul, Turkey.
Getting parts over here is an ordeal.
Considering he fact that valve seats are fairly inexpensive, I thought it would be cheap insurance to have them at hand if the damage is extensive.
They have only been handled once. By "handled" Imean I really do not know if the
I'll see once I have the head off and taken apart.

Ah, gotcha. Good news is 98% of shops grind the seats. I bet they can be reground.
Good luck moving forward. Have you found a better machine shop to do the work? I feel your pain, I have had shotty machine work done before too and paid a premium for it. I now rebuild cylinder heads myself which costed a lot to buy the tooling to do.

And the saga continues...
I have been running the car with all new valves, seats, guides and new light double springs since my last rebuild.
Here is the funny part: Now, valve clearances are GROWING.
I checked the lash, and especially exhaust valves have too much, up to 0.42 mm.
What's interesting is, I am hearing the valves tick at low speed decel only.
Head will come off one more time.

There are quite a few people here who race and otherwise abuse Supertechs with no problems.
