906 casting vortec heads with screw in studs and guide plates. they have been sitting for a while and should be gone over before using, but may be fine as is. They are drilled for a standard 12 bolt intake. I have never used them but Id imagine that the valve guides were machined down for higher lift. The valve springs look much beefier than stock as well. $200 or best offer.
