Default 72 with ZZ383 exhuast

I've decided on Jegs for my zz383 carbed motor conversion

View All JEGS Premium Metallic Ceramic Coated Headers

Metallic Ceramic Coated Long Tube Headers and pypes 2.5" exhuast out the back.

This is a weekend 4 speed street car with a trip to Firebird once a year. They should be good for as long as I have the car. No?
I'm in AZ with no snow and very little rain

Don't go with a 1 5/8 inch header on a 383. You will need an 1 3/4 primary.

Got a ZZ383 in the shop that ran 11.90s with 1-5/8 headers. Seems big enough!
