Just now I got my head after rebuild. There was exchanged valve guides. Valve seats was polished with valves for new position inside guides. And I have noticed that now, after polishing, the valves is more lower inside the seats then they was before. I know that hydraulic tappets should compensate some difference of valve clearance, but I want to ask is there some limitation for valve seat height? Or may be there are some other risks related with this?
Thanks a lot!
