Wake up a 1968 318...

Well, I don't know how easy it is to get to the freeze plugs on your heads. I once had a Duster 340 that started leaking from a freeze plug at the back of the passenger side head. Looked at it a while, then decided it was gonna be easier to pull the motor than to pull just the head on that side. Got the motor out and back in all in one day. LOL, probably would take me a couple of weeks these days.
