Between the cylinder block and the head on an F2 there are 4 knock pins and 8 cylindrical shaped rubbers that are called "Packing,cylinder stud" on the parts diagram. See first picture.
On the top surface of the cylinder block there are 8 holes that will accept both the knock pins and the 8 "Packing, cylinder studs". See picture 2.
I am interested in knowing which of the 4 holes the knock pins should actually be located in?. They will fit in all 8 of them but there are only 4 pins.
Also when seated in the holes the knock pins sit proud of the surface (see 3rd picture). I have not had the cylinder block machined. I have read on this forum somewhere that they should sit flush with the mating surfaces so wondering if I should shave them flush?. The gap from an eye measurement is about a mm and the head gasket I have is slightly thicker than that.
Pretty keen to only do this job once for now, so thanks in advance.
