1981 GPZ550 Head

I broke a bolt in my cam cap.... I know I know. The machine shop says that they can't fix it. Does anyone have a head (in the US) that they would be willing to part with? Feel free to text direct Aaron at 760 953-6684

Please post a picture of the carnage. It may not be unfixable.

I agree with Texas, you may be surprised at what is repairable

Oddly enough, the head has already been replaced.  Quick work, thanks guys.  I actually broke the bolt and then broke an EZ out, trying to remove it.  Shop say the bearing surface is shot.  It would require re-welding and line boring on the cam bearing. No worries.

For future reference, broken studs, drills and taps etc can be removed by a process called "EDM" (spark erosion) for around $40 per hole by a specialist
