STARTER/FLYWHEEL QUESTION

I had my 340 rebuilt in my 69 Swinger. After 600 miles the clutch started grinding when the pedal was fully depressed. It turned out the Bell Housing was misaligned by .019” total and the clutch disc was hitting the flywheel bolts (the builder told me he aligned the BH as I requested). I should note that I have turned over the engine probably hundreds of times with a socket wrench because I had great difficulty getting the B.H. aligned with offset dowels.

I had the transmission out and before I put in another clutch, I noticed that the solenoid gear doesn’t retract from the flywheel unless I move the damper bolt slightly with a socket wrench. I’ve had the same result with another starter. Same result with the original dowels. Does this sound normal for an engine with 600 miles on it because it is still tight or do I have other issues?

Thanks for your help.
