Trickflow heads for sale, 195 cc intake runners, ported polioshed, bowl blended, radius blended, unshrouded valves. They are aluminum with titanium valves and if you buy them I will even throw in a pair of roller springs. I am selling this heads to buy new heads for my new engine. I will sell them for 800 which they haven't been used as of yet and the exhaust ports have a satin finish on them to help aid with the use nitrous oxide.
