what grit sanding rolls do you use? and how do they work? i am hoping to get the windstar and port my lower this spring. I have done a little gasket matching work on couple of friends cars, not v6 mustangs, but I am jc what works best. In your opinion.i dont use anything flexiblejust a dremel and the sanding rolls
oh and also, I am not porting my heads so should I just leave the lower part of my lower intake so it is tapered into my heads, or just do them. I am planning on doing my heads in the future just not now because I do not have enough money.
