Looking good! You may want to mock up the alternator and see how it fits. I'm running a LA 360 with Magnum heads... Front of the motor is off the original '68 318. I'm running a later model "square back" alternator, and it was necessary to grind the front end of the passenger Magnum head for the alternator to fit right. If you are using the '69 style alternator you may or may not have this problem, but easier to check and remedy before the engine goes back in.
