my concern if I gasket match it, the matching will have to go very deep into the manifold, the head port seems that much bigger (max ported eddies), if I just gasket match it, it will look like a "cave" in the manifold and might be worse than just leaving it alone?
I think it would end up being a job I would have to farm out (porting the entire intake). If the matching only gives me 5 horsepower or so, I'm not gonna do it - not looking for the last available ounce of horsepower for this application - the only reason I have this manifold is it already has the efi injector capability (car will be efi).....
Thanks for the info so far!!
