my read on this was he has a 15 year old son that wants to get has feet wet with out a lot of $$$$$$$ so he as two head cast that work fine but numbers do not match so i said it happens alot if the chamber and valve size is the same then there be ok . ? is this rigth?? so that went from two heads out side miss match to hell DAD buy new heads ?? as jerry said they do not cost that much to rebuild and i would concur .if the heads need work then see if the machine shop can match the head if in good shape . then ask the guy whats the cost of a stander valve job and you have a budget . he may throw you a deal i know a guy that has done that were all machines are all set up for small blocks and as a surplus of parts. i am not going to say on here the time it takes.other then this it is very fast moving forward job i keep most all parts in the shop for small jobs like this seats .valve .guides.seal. in the shop. so there no stopping . the mag/ cleaning of heads they will be in the hot tank and jet wash longer that it takes all the time. to put all new guides in and a valve job and deck the sbc heads are easy as pie with the machines set up. i roll threw sbc heads . now bbc with iron head beat the hell out of me
