I rework a great deal of SB2.2 and Mopar "takeoffs".  They can be made into a useable head for many large cubic inch engines or smaller engines turning lots of RPM.  One of the shortcomings of a "takeoff" is the exhaust port.  They are on the large side for a drag application.  However, the intake side can be made just as killer as anything current.  Pricing starts at $1000.  Please email with questions.
