I'm trying to weigh my options. Got them with a set of 63J heads 20 something years ago. Storage was compromised and heads are missing but they left the rockers and finned valve covers. The set still has the alum. stands that encircle the shafts as the old heads were milled flat. I'm sure they would have to have new spacers or something. It has small springs between rockers and stands. I guess they could be used as are if the heads were milled to the correct height.
I'm not sure if I'll ever have a use for them but wonder what they are worth and if I should get rid of them.
