Hi there Mr Scotty,
My dads an Australian who watches your youtube channel. I have a September 2001, VX , Holden Commodore. 238121KM on the clock, Automatic. I have water in the engine oil. 😭 My dads taken one head out and it looks like there's no cracks in that head and the gasket was OK other then nearly all of the water ports were almost blocked up with a pin hole size flow And the big ones were completely blocked. He can't get the rusty bolts off the bottom part of the manifold to remover the other head and his broken 1 bolt already. Any tips on how to get them out. He was thinking about heating them up with a blow torch . But his not feeling like that could be the best way to do it, we have also used WD-40. He thought he would ask you for your suggestions. 🙂

Well try the blow torch but often you're going to have to use oxygen acetylene torch to get them to glow red hot to get them off and even then they might break when they get rusty heat. Is rosy only option if they're really bad
Soak them down over night with PB Blaster, then put the torch to them.
