New Small Block Headers
The header that fit the best over and over again have been the headers sold under the Summit Racing brand header. Which, if I’m correct, are made by someone else as in a big name in the industry.
Flanges are 3/8 (love that!) so you’ll need an1/4 inch longer bolt, ARP has them, all tubes cleared on both sides.
Even better! The Summit racing dual exhaust kit bolted right up.
But the kit needs some minor trimming to fit best and suite the exhaust tips or where the exhaust pipe ends. Some points are a bit close but clear and they do not hit anything.
I did swap out the kit mufflers for the Summit mufflers that stay 2-1/2 inches in diameter pipe size inside the muffler. The tail pipes will be trimmed down later.
