This cylinder head is a bargain for the power it makes!  Over and over it has made 650+hp out of 383's.  550hp out of 383-400 pump gas engines. Dedicated small bore.  Don't be fooled by the price and the import casting. This is a great cylinder head!

"I would not call this head cheap. I would call it less expensive. Its not cheap in any way shape or form.  That’s a bad ass head!"- Darin Morgan
