I have a pair of the Chapman ported Stage VI heads from Mopar Performance part P4876383. These are the bare heads and they cost $2475.96 Each at Summit or Jegs. Closer to $2800 each from MP. These have a raised intake runner which allows the use of an RB(440) intake on a B engine. They can be used on an RB engine but you have to use a spacer on the intake. They use an 11/32 stem long valve on the intake. Machined for 2.18 intake and 1.81 exhaust. These are brand new, just opened 1 box for the photo. You can search these on the web for more technical info. I would like to get $3000 for a pair which is little over what 1 head costs from Summit. These are great heads for the 451 low deck strokers. Located in Louisville Ky.
