Champion Aluminum GN1 heads for sale. All ready to go and bolt on. They are 14 bolt heads that will work with the TA block or stock block applications. These heads have been fully ported and machined with about 40 hours of machine work. The bowls have also been reshaped. The heads flow 252 CFM @600 lift on the intake side, and 205 CFM @ 600 lift on the exhaust @ 28" test pressure. The exhaust valves were upgraded to Inconel valves to take the added heat. Dual valve springs upgraded. These heads were purchased new in 2023 and have seen very little run time, approx 12 Dyno pulls and 30 minutes of street driving and were never raced at the track. The heads came off the engine two months ago and went to Champion for a fresh cleanup. Richie went through everything including milling the deck surfaces and a new valve job and he will stand behind his work. $4500 for the heads without the rockers, and $5200 with the rockers.
