Thanks guys. I have built a bunch of engines, but the last time I touched a flathead was over 40 years ago. Now learning a lot about them. I found some nicks on the original rods, and ground them out. Stress risers are a disaster waiting to happen. I decided that I didn't want to trust them at all. The 8ba rods were easy to come by, and I preferred the inserts over the floating bearings. Also the 8ba rods are a little stronger.
Unless I am sure about using the 8ba rods, I had best just get a set of the 59ab rods.
What are the concerns about the full-floating bearings?
