Description

Wtb! 

U67 cylinder head with square ports

 

For my 1976 Datsun 710! 

Would very much like to get it back on the road.

Mine is warped 😞

Does the cam turn freely if you take the rockers off? If yes then you can have the surface milled down flat. Maybe $50. Hell I had a U67 that a high spot in the middle that you could slip a 0.015" feeler gauge under a straight edge. That's almost 4X the allowable limit. I glued 80 sand paper to a glass door from a stereo cabinet. With the rockers all off so the valves were all closed I pushed and pulled the head across the sand paper and ground it down in about 40 minutes. Finished it with 150 grit. Cost me $7 for the paper.

 

The low areas are dark.

Every 20-30 passes blow the granular aluminum dust off the sand paper or it acts like ball bearings.

Not a mechanic 😑 but sent the head to a machine shop whose opinion was that it couldn't be fixed because it was actually warped and shaving it down wasn't going to help.
