Don't feel bad.
When I did the cam break in on my Galaxie, well.....
I wired my fans backwards so there I am with an engine at 220degrees trying to pull the bullet connectors off and flip stuff around.
I may or may not have burned myself on a handful of things.
Course cuz it's good common sense, I decided to fire the engine and do cam break in on a day that was 104 degrees.
I forget the rest of the details, but it was one of those days where "If it coulda been done in a way to make life harder, it was done."
Like the "old man" used to say when I'd mess up: "Experience. It's that thing you really needed 30 minutes ago, but you got lots of it now."
