Well, the machine shop just notified me that my tired 235 is already bored .060 over and the crank has been turned .010. What is the recommended maximum bore for a 235 ... is .080 ok for a daily driver?

..... or should I just start searching for another 235 or a 261. The 848 head on my 235 is in very good shape, per the machine shop.

I have all the external parts for the 235, including flywheel, bellhousing, starter, etc.
Can those be used on a 261 if I find one?
