0-port shorty headers for Dutch formula 400 needs your help
Dear Gearheads,
I want to install Edelbrock RPM cylinder heads #60599 with round ports on my '79 formula with a 400 engine. To avoid header fitment troubles I consider to use shorty headers. They should have round ports due to the RPM heads. I'm looking for good quality flanges and stainless steel. Your suggestions please. Good quality alternatives are welcome. Thanks in advance, Gerrit |

Hey Gerrit,
Generally with Pontiacs the majority of people in your situation will use an improved reproduction exhaust manifold from R.A.R.E. A shorty header would not gain anything over one of these ram air manifolds from the testing that's been published. But to answer directly, I have not seen any production round port shorty. It is counter-intuitive to choke set of HP heads something like this  (in theory)

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
