I have some loose contacts at Durabond, so I called them for you. They currently have 13 back orders for DUR-P-4R1 bearings. Those are the .010" oversize bearings. They were waiting for 25 backorders to make the sets. I would think Butler would be in for 12 sets but don't want to bother calling them unless you want to go that route. That would require the cam tunnel to be line bored or honed +.010. Not a big deal if the shop has a mandrel the right size and a small enough dial bore gauge to measure them. Unfortunately, I do not have a mandrel that small at my shop or I would just do it for you. That would be the easiest fix though IMO to save the block without getting all exotic about it. Durabond said 4-6 weeks once the order threshold has been reached for the order. Let me know if you want to proceed in this direction. Good luck.
