Tom,
Call Johnsons (since you're local to me) and take the heads to whoever
they recommend to test them. If the heads check out OK, then you only
need a head gasket kit. I've done it several times. Almost no need to
have them machined. Johnson's has the head gasket set you will need.
Not that bad a job. Takes a weekend.
Jim
