i found some rust in the heads

nothing mayor, but i was wondering if i should use a seafoam treatment or do nothing at all?

 

Are you sure it's rust? Not just a rough casting? Or are You talking about the rocker?

 

I don't think it's anything to worry about as long as its on the rocker arms and not any place else.
Has this motor been sitting awhile?

 

my bad

i didnt know the name of the "rocker".

 

After looking at the rockers more closely I would think that someone replaced the rusty ones, as they are just slightly different than the ones without rust on them..............don't think there is a problem as long as the motor is running ok.
