In my local paper, there is an ad that reads, "235 head all reconditioned with hardened seats" I do not know what cast numbers it is yet. Nor do I know if there are new springs, valves, etc. I'm assuming original parts with hardened seats and a valve job. Anyone have an idea what dollar range I should offer for it if I decide I want it? It was told it was done by the local reputable experienced engine builder. Thanks.
