I have a set of these in my garage assembled but I am going to toss the springs, locks, keepers and retainers as I am going to sell them bare.
They are casting #3964291 closed chamber rectangle port 107cc heads thats came on a L72 1969 427 camaro. They were also available on the 1970corvette and chevelle LS6. They are ported and epoxied for drag racing as they were on my old SS/DA which ran 9.60's I dont see why you couldnt get at least $1200 for them bare. Not sure though. I am going to EBay them but need a good reserve amount but I am not sure.
