Ok..so a bit of an update. I got the car running right with a lifter and rocker issue resolved. Drove it for weeks with no problems while it was for sale. Day before auction to end I was driving it and lost oil pressure to 20 psi when hot. I would in no way even consider selling with a remote issue that keeps coming back in the top end of the motor. Ended the auction and jerked the motor. I had sold the motor above already so when I got the next 360 back from the machine shop it will end up in the car instead of the 73 Duster. Then back up for sale with a fresh motor.
