I have to use the stock head which has 3 simease intake ports (1&2), (3&4) and (5&6) and 4 exhaust ports with the center cylinders (2&3) and (4&5) simease. The end cylinders (1&6) have individual exhaust's.
Now that everyone is finished laughing here's my problem:
Does anyone have any knowledge about how to build a good header for this engine? I plan to dyno the engine and tune the exhaust but I'd like to have a good starting place to work from. My dyno time is unlimited and free so dyno cost's aren't a problem. I'd just like to keep my learning curve as short a possible.
Does anyone know if Pipemax addresses the problem of simease ports? Does anyone have a link to Pipemax?
Thanks for any and all help,
