Intake is/was a holley pattern that was nicely machined for qjet..It's original aluminum intake ,with machined plates on ports to adapt hi-deck .Even though these are good running motors.I'm thinking the value is in the sum of the parts .They were closed cooling motors.The valve covers have 540/575hp on them .
