Yes, the rocker carrier frames have a countersink recess in the bottom to
squish the O-rings against the top of the head and the cylinder studs. There
are four up there.
Since you're not desperate and you'll wait until winter, I would do the job
properly. After pulling all this stuff off, I'd also pull the cylinder to
replace the base gasket and the two O-rings down there (see, now there are a
total of six, just like the studs). The upper and lower studs have O-rings
at the bottom of the cylinder between the base gasket and the cylinder.
Again, the cylinders have a little coutersink recess to handle the squish.
After you do all this work, you will need to torque the heads and adjust the
valves 3 or 4 times over 2,000 miles. What a waste to do it all and then
discover that an old, hard base o-ring is now also leaking. If one is hard
and cracked, then obviously all six are suspect. Do the whole thing.
