Fresh 993 Heads

I have a set of sbc 993 heads for sale, just back from the machine shop, 3/8 screw in studs, 71-72 cc chambers, just been surfaced and 3 angle valve job, ready to bolt on. $300 for set obo, located in Arcadia,Fl 34266

Have these heads ever been milled? Think they would work on a 383 motor with pop up pistons?
