yes they do. i lost the flow sheet that came with them. These are Stage II 1020 Superflow Bench 3.905 Bore with 2.055/1.57 valves and 59cc combustion chambers. The $995 heads have they have cnc'd intake runners stock valves. Mine have upgraded stainless valves with a 5 angle valve job. so they should outflow those heads but im not sure by how much since i lost the flow sheet. If they were still selling those heads for $995 that would be a good deal but that sale ended almost a month ago. heres the link : http://www.patriot-performance.com/w...05234&DID=1225 my heads are PN 2033Quote:
