318 Magnum first fire...timing?

As far as the freeze plugs, the one in the picture is not far enough in. Looks to be just level with the block, you should see the taper of the hole. You may be able to pound the plug in further maybe an 1/8 of an inch or so. If it still leaks...new plugs and I would use Permatex Aviation Sealant.

He has the deep brass plugs so flush is fine and really common.
He also mentioned the motor is already in, which means a pain to get to.
For the super minimal issue he has, I would advise to not mess with them or things could get worse fast.

If the motor wasn’t in yet it might be worth doing, but my experience says they will stop leaking pretty quickly as is.
