Default What size threads

what size threads are in the holes just above the exhaust manifolds on the 317 heads? i need to bolt my dipstick to something and one of those holes would be perfect but i have no idea what thread it is and none of the spare bolts i have fit it.

If it is the same size as the oil dipstick bolt on the 853/241/243 heads it should be an M10x1.5 25mm
