has anyone ran a hondata intake manifold gasket and had port work done on there intake manifold and there head?
did you shave it down and if so how did you do it

Yes, and it is the same size as the gasket. From my understanding (and I could be wrong!) the size of the ports is pretty much left alone. It is inside that all the work is done. I have seen a couple of heads, from different porters, and they all fit a stock gasket. Someone let me know if this is wrong, I hate to be a mis-informer!
