I’m in the reassembly stage of my 4.2 rebuild. It’s the original engine in my early series II SWB RHD. I don’t have the ID # in front of me. I am replacing all of the head studs so I’ll never have to look at them again. Out of the 14, 4 are short but I don’t know the exact length. Out of the other 10, I know at least 1 has a dowel - will the dowel studs work in every hole?
So to recap: 4 short - exact length
10 long - exact length, dowel(s)
