"treated to a performance valve job by JMS Machine"
Open to interpretation I guess, but it isn't a stock type valve job. At least 3 angle possibly more. Either way doesn't make sense to do a 3 angle and leave the ledge without blending it into the bowl.
Performance valve job means they at least did a little bit of blending into the bowl maybe even smooth out a little bit of casting here and there. Gasket match intake to head, nah they didn't do that.....
