The ones that position the head to the barrels are ok like wise the two that locate the barrels to the crank cases .these don't locate anything only the rubber seals as far as I can see
K2-K6:
I had to get out my manual to see what they do so sorry if my last post was a bit off and may have been talking at cross purposes with you.
Going from the outer most studs, the two front ones have the location dowells for head position, then the next pair of studs in clamping at back and front of Cylinders 1&4 have the sleeves you are talking about?
Honda manual describes these as "head gasket dowells" from which I get they are principally giving accurate location to get the fire rings centered over the bores, think there is more tolerance around other stuff like oil ways.

I've been reading some were that Honda fitted these help with stop head gasket leaks .
K2-K6:
Interestingly as ukpete says somewhere else they deleted 4 of them on the F2 as compared to it's direct stablemate the K7 and all the previous Ks.
The oil running back down the studs is not really pressured, some people seem to have better succes at building them without leaks than others and you also get into the debate of using sealant or not and which type.

Hi will this sealer be ok for for the rubber pucks .and another little set back .the main location notch pins I have for the head to barrels are the wrong size I've measured them at 19mm should be 18mm .they have seen better days too .
