heads for 340

A few yrs. ago I made the mistake of rebuilding a set of stock heads that needed everything and having a comp. valve job done on them. About fell over when I saw the bill. Machine work ain't cheap. Could have bought a brand new set of RHS for only about $200 more and they would have out powered the stock heads. If it were me I'd sell what you've got and put the money towards a set of RHS heads.
