I just received the mounting plates for my tri-state 4 into 4 headers. The holes for the exhaust ports are smaller than the ports on my heads (Edelbrock). The enclosed gasket is way wrong as well.
Anyway, I'm thinking about enlarging the mounting plates to fit the exhaust ports, otherwise there will be a big restriction (and using better gaskets). However, I don't know what it will take to open the ports. Has anyone out there done this? If so - how did you do it?
Thanks
