Does anyone have any experience or recommendations for big block headers. I’ve got my 454 broken in on a dyno and they gave it a tune and a few pulls. I’m getting ready to drop it into my 72.
I’ve got all the big block parts required except the headers. I’m looking at Pypes Performance Exhaust HDR100S, but don’t find any reviews on people’s experience with them.
Anyone out there use them or have suggestions?

I bought a set of Hedman 68196 that also have the round port flange. Sold them because they don’t fit my 336781 head exhaust ports.
