AFR 195 aluminum heads. They have been ported professionally. Have a fresh surface job on them that was done professionally as well. Combustion chambers measured at 67cc. Valves have been leak checked. Springs were for a mechanical flat tappet. AFR said they will support .600 lift and 6700 RPM. They came off of my 400 sbc. They were inspected by an engine shop. No cracks, not warped. My new motor will not support these heads. They are great performance heads. No low ballers and no tire kickers. Brand new these are $1600 heads. If you have additional questions text me.
