Heads I cant win

Just my thoughts on heads.
A race shop would want to put as many new parts - valves, springs, keepers, seats & guides into a cylinder head as they can. Their reputation depends on their quality and "no problems with their product". Thus $1000.00 bill.
I'm sure someone could get your heads useable for less than half ot that.
Aero Racing head prices are good for what you get & you could sell your 340 & 360 heads and recover some of the money.
Do you want to sell your old heads?
