    Gang-

    I'm considering some port matching and mild smoothing of the runners on a set of SBC heads. I did a few sets back in the day, but it was pretty much a "by guess and by golly" deal. I'm familiar with some of the basics (machinist's dye, etc.), but it's been about 40 years since then and I wondered if there were any new techniques, tools, etc., that I should know about. I used shaped stones back then. Are the carbide cutters the way to go now?

    Just looking for info pertaining to doing decent street heads - no "pushing the envelope" or CNC stuff - strictly low-buck work that I can do in my garage.

    Comments? Tips? Advice?

    Thanks in advance.

    Mike's article is a great one, and may of the same principles apply. Basic gasket matching, smoothing of casting lines and sharp edges, and an 80 grit polishing should do you just fine
