[Determined]

Hello everyone,

Yesterday I reassembled my heads after having my valve seats cut and valves reground plus some I had some thermal barrier coatings applied. My question comes late but I reinstalled my valves without any lube, the moved freely up and down with no binding and I installed the white valve seals as well. These are the double spring type which I believe to be better than the OEM ones. The valve moved well with the valve seal in place also, do I need to disassemble to lube the valve stems? My Bentley manual made no mention to apply any lube nor did Wayne's Porsche rebuilding book. Opinions??? Pictures below:

Thanks,

Alex
