Why spend $3,000 or more on your factory cylinder head in porting and machining, when you can have a brand new performance casting for less! The new 12v head from Hamilton Cams solves the issues with the factory casting. Here are some of the benefits.

- 1.850" intake valve, 1.750" exhaust valve - 45 degree intake and exhaust valves. - 230 CFM intake flow compared to 138CFM on the OEM casting - 191CFM exhaust flow compared with 150CFM on the OEM casting - .100" thicker deck for better cylinder sealing - Thicker port walls for extensive re-shaping potential - Direct bolt-on - street trucks have seen 50hp increases, more on competition engines

Not happy with the flow? With an individual runner manifold and a port Job over 300CFM is possible! We also have custom cams available for pulling applications with this head. Don't forget to get the head o-ringed if you are going to be running boost pressures over 45psi. Also, if you have under .320" cam lift or .550" valve lift, there are major gains in flow to be had with a 30 degree intake valve and seat as opposed to the 45 degree valve angles the head comes with.
