Paul as far as I know C&L doesn't require a jumper wire atleast the direction on my 76mm don't say that. I got rid of my 75mm Pro-M for the C&L I hope I made the right choice, it does look nice with the alum discharge tube.
The only thing I had issues with with my old set of heads "which nobody at Holley really knows what they exactly were" was all my exhaust valves just kissed the pistons on the out side edge of the eyebrow. Now on the new heads I don't have that problem and I have plently on clearance with the Anderson grind which is pretty decent. I don't think he will have any problems, when are you guys doing the install? How so they AFR heads look?
