Just wondering what type of headers people are running with big block conversions? I will be putting a 454 .o30 over for 461 cubes. I have heard quite a bit about the Hooker super comp headers part number 2226, but also heard that they are not the best set out there. What are some heddman partnumbers or any other manuf.??? Any help would be greatly appreciated..

 

I've heard nothing but good stuff about the Hooker Super Comps, so you probably can't go wrong there.

The 1.75 primaries on those headers are pretty small for a big block.
