Hi all, im rebuilding my super A, and im now down to the head. this head has seen a lot of water and the valve spring caps have a lot of rust. so i dont think i want to reuse. im looking in my parts book and its showing 2 different caps, one just says valve spring seat upper, and the other says roto cap. now, all my caps are identicle, and the roto cap looks like its for exhaust only, so in my case would i not use the rotocap? just stick with the regular for all valves? the next question is, my dealer wants 10.96 for each one, is there anywhere i can get this aftermarket, or anybody got some good shape and used? if so i need the top and bottom

thanks for any and all help.

Rusty explained that very well. Even garden tractors have those rotators due to high heat in air cooled engines. If it was my tractor I would use them. Hal

The rotocap was designed to be used on exhaust valves. Its purpose is to rotate the valve a small amount each time the valve is opened so that the heat will be more evenly distributed over the entire face of the valve, and not just allowed to build up in one spot, which would cause the valve to burn and erode away. For an engine that is working its little heart out for long periods of time, the rotocaps would be a good thing to have. For normal, light work, you don't need them.
