That's part of the thermactor(air pump) system. Actually it looks like a Delete set-up for the air pump. Normally they are a T and the open part runs to the air pump. It pumps fresh air into the exhaust ports of the head.
Thats odd... you just have to cut the ends off and put them on backward with some RTV
Thanks Kurt, if it has the passages I'll just put that back on, if not then I wont.
Another thing is should I treat the cylinder walls that are exposed and the top of the pistons with anything at all to prevent any rust or are they fine in the open air like that? I wont be putting it back together until this spring.
