Hello. I once bought, for the first and last time, a paste for lapping valves, on an 8-valve cylinder head, so I barely had enough! I didn't throw out the old ones well, there are enough of them for two or three GBTs. Check right away, they're kind of half-empty. I don't know, maybe I got such a party. There was no point in taking him back, he took him to the village... Good luck to everyone.
