Update
Dowel pin remove and head sitting on bottom end
Carbs cleaned and painted
Ordered headgasket & timing belt.. Garage Discount FTW!
Was told by previous owner the car was drinking water
i reckoned it was the headgasket but no signs of warping
upon further inspection turned out the water pump housing was in S**t
so took it off and the f**king dowel in the housing snapped into the engine
MY F**KING LUCK
