Does anyone know a decent 3/4 " primary, equal length header that will fit a 69 Camaro with PS. ???

Depending on the particular heads in question, round "stock port" headers can indeed seal over a D-ports, but GM D-port heads (and aftermarket ones that mimic their exhaust port geometry closely) will exhibit shrouding at the roof of the port, in most cases, when such headers are installed on them. LT1 and LT4 heads feature exhaust ports that are raised .100" from stock and the exhaust ports of the GM Fastburn heads are raised .200". For a flange/gasket match that is ensured to seal and prevent shrouding, you really need a set of headers with a "D" port flange configuration (like what is shown in the attached photo). I work for a manufacturer that is about to release exactly the type of header you are inquiring about for your application, but I can't tell you who that is without the site administrator thinking I'm trying to sell you something (even though I don't work in sales at the company in question). If you want to send me a PM, I'll be glad to give you any fitment or technical info you want on the headers without having any interest if you buy them or not. Good luck in your search [IMG]
