360-(974) Heads

Have a question here. I have a warmed over 360 I want to put into my 67 Notchback. Does anyone know anything about these heads. I've looked all over the net, and can't find anything about them. Are these heads worth keeping? According to the guy I got the engine from, there's been a little port work done. They have 2.02/1.60 Milodon Street valves, Comp springs and retainers. all mated to .125" quench dome KB [email protected]. Will it be worth doing some more work on this combo. Thanks, Mike V.
