I just had the '88 cyl head /cyl modified by Jerry. He can machine out imperfections up to a point then your head becomes a conversation piece. It's not cheap as the coolant passages are reduced on the exhaust side, squish /dome modified, sealing surface milled flat, oring lands machined in. It came with orings. Expect to spend two Benjamin's  +k2

Yes its money well spent and a critical mod/upgrade for the 500's. Send it to Jerry............

I will get hold of Jerry after the holiday. I have a spare head that I cxan send him. Looks to have only minimal damage to the gasket surface.

Jerry, I think I remember you talking about heli-coils for head studs to repair damaged threads.
Is that the thread insert you prefer for head studs?

I prefer Heli-Coils to repair threads in aluminum.  We see too many problems with "Time sert or Keen Sert" staying in place.

The head looks like it would be a good head after the gasket surface is machined.  You may have problems with the head gasket sealing on this head gasket surface.

Im not using this head now. Its an extra that came with the Z when I bought it.  If this head is a good canidate for you to work on on I dont have to to rip apart the Z right away.

Problem fixed. I sent the head to Jerry to be o-ringes and the squish fixed. Top notch work there! The last head stud on final torque pulled up in the head. Un believable. I checked them for holding torque before I sent it to HPR, and HPR checked too. Called them up and was told how to fix. Lucky I have a friend close by with a mill and a nice assortment of heli coils.
