Porting cast iron manifolds I have a set of 2001 manifolds that I want to port out. I don't have any air tools so I'm going to use a dremel tool.
Any recommendations on bits I could use? I tried a silicone carbide grinding stone bit but that lasted about 1/2 through one of the primaries. I found a set of Olson carbide bits on Sears' website. Would these work? It's like $60 for the set so I don't wanna wreck them.

Re: Porting cast iron manifolds There is a company called "Cylinder Head Abrasives" in Rancho Cordova, CA. They have a huge selection of solid carbide porting tools. I can't remember their phone #, try this website www.ruffstuff.com/ Cylinder Head Abrasives <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Also, have the inside of the manifolds hot tanked and sandblasted before you start grinding. You will get much more tool life from the carbide burrs. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />
Good luck,
