I'm not a fan of putting a part like a head on an engine if your not totally sure how good it is. Nothing worse than putting an engine in a car only to see it smoke or worse. At least get a cheap valve spring compressor and clean and inspect before you put them on.

b4 i put them on i plan on buying the cam kit from comp cams. it comes with springs, retainers, seals, for the heads so that should freshen them up a little at least. i might need to have them slightley milled. Any idea on around how much it would be to mill heads?

Be sure to check those heads out before you buy anything for them. Chances are that they're going to need the guides redone and maybe new valves. You'll need to have hard seats installed if you plan on driving it on the street. Start adding up all this work. You're close to the cost of a set of sportsmanII or iron eagle heads. The 993 are junk for performance work and just ok for stock use.
