Thats a tough call really, is that 500 bucks somewhat disposable? Take what anyone says when they are selling used parts with a grain of salt and gather as much knowledge about what you are buying before you buy. Simple things in this instance would be to take an intake and exhaust gasket with you and line them up to see if any port work has been done as far as gasket matching goes, thats first. Definately take a few random springs off and just check valve guide wear by moving the valve around in the guide. A quick visual of the valve seats is simple and will tell you real quick if you are buying junk.

Just cause someone degreased the heads and wiped them down dont mean crap. I know you probably dont have the tools or access to them but for instance what I would do first is take a bore gauge and micrometer and measure a few ports real quick and find out who's lying or not. Guaranteed you could find stock intake and exhaust port dimensions. Or pretend you know what you are looking for and throw a few curveballs at him and ask if the roofs were raised or if the short side radiuses were worked on. Wipe of one of the valves and check to see the radius on them, anyone doing porting is going to do a valve job. Use your gut instinct, price is second.
