Odd machine work on cylinder head.
« on: March 09, 2019, 06:07:46 PM »
I bought this 750 head on ebay and during disassembly I noticed this "machine work" on a valve guide bore. Would you guys proceed, or would you call it a day for this head? Doesn't seem to leak, but I'm wondering about strength/support for the valve guide itself. Thanks

 Not seeing anything to worry about.
 Is it a 410 head ?

Yes, its a 410. I kind of figured there wouldn't be any issues, but I wanted to double check before I potentially wasted any time on the project.
