Would you reuse it?

You asked, "would you (like me, AJ) reuse it"

My answer is; "yes I would".
the number-one reason being;
cuz on a slanty, it's like in your face easy to change later.
Number two reason.
I ran a 10 year old one in the early70s, and an even older one in the late 70s, and
I ran another one from 1994 to like 2017 or so, going on 300,000 kilometers.
So, there's that .............
I've run old slantys , on again/off again, almost since I got my license in 1969. Not one chain ever did I change. 318s either for that matter. But my Brother in law lost one. He called me up one cold winter day whining that his 71 demon wouldn't start, which I traced to a seriously jumped chain. Butcha know what? After retiming the distributor, I got it to run at WOT and like 400 rpm lol. Brrrrrrrrrrrrrrrrr
