Good flowing head, as is. Fast-burn chamber design and port design derived from the LT1 head. 64cc chambers. Intake mounting is different from other head designs, which will require a special intake manifold. Scoggin-Dickey has a kit available.

Friend of mine did a set a few months ago. Some effort was put into them, but no angle milling or anything that crazy like that was done on them. The intake flowed 280cfm at .500" lift, not sure on the exhaust numbers. Those heads died out at lifts above .600". I am sure if you mill the head and do some other mods they can flow a bit higher and maybe give you a higher rpm limit, but not sure. A really good head if you put some time into them though.
