Cylinder o rings

Dirty
Hey guys, it's been a long process putting my 78 F motor back together. I've been trying to find out if these o rings are supposed to be here or not.  
I know the 11 mm ones on the inside studs go there but I can't find in any manual if the next outer 4 studs get rings. I thought somebody here had a great post about a 78 rebuild but can't find it anywhere. Thanks guys.

That post was deleted by the poster under mysterious circumstances. However your engine uses 4 O-rings between the case, and cylinder, and cylinder and head. on the 2 inner rear studs, and 4 larger rubber rings on the 4  studs between the two cylinders, between the cylinders, and head.

Ok that explains why I couldn't find it!!  I've seen that diagram but it doesn't show 6 plus the 4 sleeve o rings between block and cylinder.  You said the four inner studs get um. Mine has 1 on each center rear (total of 2-11mm)  and 1 on next outer left, right, front and back stud (total of 4-6or 8 mm tight on studs). Not sure if I explained it right but it sounds good in my head. In my pics you can see I'm pointing at them. I'll have to look when I get back but I don't think I have new ones in my gasket kit that is for a 78 ss.

The O-rings in your picture are correct. They are No#6 in the diagram.

Alright. Thanks Tools. Looks like I have to make a trip to parts store for some orings. There is only 1 ring in my kit that looks right. Thanks again.
