Most engine rebuild kits give you 8 seal so you have 4 extra to use if you mess several up before you get the hang of it. The exhaust valves have the groove for the seal but since there is no suction when the valve is open they would server no purpose. If fact I installed seals on the exhaust valves when I did a if frame rebuild. Twenty years later when I did a full rebuild the seals had shrunk to almost nothing. The intake seals were still good. Grease is your friend when installing seals. [Reply]  [No Email]
