I did notice a great difference in my engine to Andy's and I'm sure yours. Mine has a low starter location and my log on the head is more square-ish looking. My casting number is AOBE or AODE. What a nice looking cylinder head. Goes good with the yellow.
He says its Casting grey, but it looks more like a camouflage FX paint. Anyway, she's up there loud and proud!
Mine's like his. No pollution/airpump openings, although I do have the EGR valve (disconnected). Mine's from a 1978 like his.
Andy, When you get close to finished don't forget to refinish that nasty looking power brake booster.
