Can I make as suggestion. If you have the engine out and the head off. Before you refit the head get a piece of stuff wire, like a wire coat hanger. Snip off a length and insert it down through the water holes in the top of the cylinder block . It should go down about 100mm , maybe more. If it doesn’t then you need to investigate why. The water gallery may choked with years of rusty crap and this will probably cause overheating. Note there should be a free passage of water from top to bottom and all the way round all 4 cylinders. It took me days to clear out the rubbish from the block on my car. It was quite alarming the amount of stuff that I got out.
