kinda hard to say w/ out some numbers....
If you caould tell someone that they were good for 30 hp...then i'd say about $250-$300
maybe more....but they will need a valve job(unless never been on car) and thats about another $150...so that put's someone at $400.
A few more bucks and coulda had some better heads. But lots of people are looking for that extra 25-30 horses for cheap.
