Any good machine shop in Massachusetts??

[MarkM]

I pulled off the old head, and went to put in the new replacement rebuilt head, and found that the new one is the same in all respects EXCEPT that the holes for the prechambers are too small !!!!.....16mm diam. in my head, 14mm in the replacement!!!!! Will send back monday....now that the car will be laid up for a while anyway, I guess I should just have my head rebuilt. Does anyone know of a good MBZ machine shop in Massachusetts to do valve job???

What is the typical cost to grind valves and seats, and install new guides and seals???


Thanks,

Mark
