68 Camaro ERL427/Mast 6 bolt heads what headers?
Hi hopefully someone can chime in with some feedback. Finally starting the install on my 1968 Camaro. It'll be a 427 ERL with 6 bolt mast heads, and an F1R procharger. Question I have is Im trying to decide on headers. I had narrowed it down to Kooks, Hookers, or Ultimate headers 1 7/8. But my tuner is suggesting I go 2" primary to 3" collector. Seems like ARH is the only company that offers those. Does anyone have any experience with any of these headers. I'll be using stock subframe and a Jakes 4L80E trans.
