honda cb250 superdream head bolts question.

i am in the process of rebuilding two 250n superdream engines both are from 1980. The thing i found strange was on the head bolts on one engine there was plastic or rubber around the base of four bolts near the threads the bolts in question where the four near the cam chain, but on the other engine there was none. I have had a look in the haynes book but it does not tell me much. So I'm hoping some one out there could shed some light on this mystery for me as to which engine bolts are correct.

hi mate
yes it right the old superdream from 78 to 79
had the bolt with oils seals on 2 blots
as i have a cb400t-e from 79 that has them
if u do not put them in the right cylinder block then it will leak

and they go on the right side of the block
hope that help u out
