FYI, the manifolds are actually water jacketed short tube 1.75" headers going into a 3" collector. However, a set of 2.25" with 3.5" collector are on their way. The risers are 18" long, no hint of reversion. Thanks for the feedback, I appreciate it. BTW, these manifolds will be up for sale soon if anyone wants them for a stockish 383/440 marine motor.
I would still talk to Dwayne.
