5 angle valve job.
2.00" Intake 1.50" exhaust valves.
210 CC Intake runner.
58cc Cumbustion Chamber,since these heads have been surfaced your looking at more like a 56cc chamber.
what kind of gains could i see with these heads a cam with the specs around 236/230 .600/.600 not sure on the lsa this is gonna be a custom grind cam and this is just general idea of the specs

 

anybody...

 

Depending on who does the heads + supporting mods, you should be around 380-400rwhp atleast...possibly more if the heads are stout.
