Far as I know they are cast bore for stock OEM.
They sell so many different types of cylinders on eBay anymore, for cheap. It’s hard telling what you have when you buy a used bike.
Yes, i had called instead of emailed driveline. Was able to get some good ideas.
Since my crank and all is solid still, it was recommended to do a 392 with stealth head set up so I can still run 93 gas and be able to run stock carbs.
Again, thank you for the help and direction. Was and is greatly appreciated
