What does this mean? Did he port match the gaskets to the cylinder head? Or do you mean it needed valve seats? Guides & seats take time & good equipment to do the job right. For sure he should of told you what the cylinder head needed before doing anything. I kinda had a similar thing with a Farmall H head. Took it only machine shop in the area, got the round around for close to 3 months. It was winter time, so really didnt need it as mows grass in the summer. Finally had enough & went in & found the head had been resurfaced. Machine shop told me they cant find valves or guides it. Did a google search while standing there & found valves/guides all over the internet. I asked why did you plain the head first? No real reason was given, asked how much is the bill? They were confused as it not done yet, I said Im done with you. Paid the bill & haven't been back in years. Ordered the parts & took to a machine shop 2.5 hrs away. They were really concerned about the head being planed already, told them do your best. Its really tough to find shops that good work, guess only thing I would ask is why quote on what head needed.
