Ryan , I would like to use the Indy dual plane, but I thought it was only available for the RB enignie. Do they make it for the 383/400 blocks now? that would be cool and my first choice.

Bob, I have the 2" step to 2 1/8 headers from TTI now, they were ordered for stage 6 heads. They are the headers TTI440-200c4. basically the 2" header for a raised port on a low deck (B)or a standard location port on a tall deck (RB)

They fit great and are currently on the car, although I dont think the heads I have are raised exhaust port heads. Thats why i thought the S/R's would be great, bowl ported but stock port window. use my H/S rockers and everything else in the kit from Indy. I can even reuse my M1 intake and it would fit if I got a new air cleaner.
