"Clear water cyl head" did some work for my shop .. They did it poor enough that we have restocked our engine machine shop. I mainly do race VW heads, and old custom stuff like Jaguar.
I am set up for service of these heads. The nice thing about the small stem valves, is that the guides are still OK. Most of the time.
I have dome two of these in the last 3months. Most of my parts come from Pelican. Nice prompt service, quality parts. I lightly grind the seats, hand lap the valves to the seats. water check the whole setup, change the seals. Usually finish with a light( 004-8) surface of the head to clean up any corrosion. If you have the head cut any, make sure that you also cut the front cover.
Labor runs about 400$,
Takes about 2 weeks for parts and service.
Parts are lifters, valves, head set, chain rails, tensioner, cam wheels.
If the bottom end is OK the cams are OK , as a rule.
Before doing anything with the head, make sure that the oil pump and screen were working, and you should consider puling the front rod bearing. If they are shot, dont waste your time with this head.
