Carbide grinding bits to port heads? source?

[SeanP]

Summit has some for $55 for a set of 4. Anybody else sell these? I am looking to port my SBC heads b4 putting them on the new short block for the tow rig.

Did you actually use those to port heads though? I bought some cheap ones when I ground out a set of smog 351 heads the cheap ones didn't last for shit and I ended up using around 25 stone-type bits...which I think worked better anyway. If you buy the carbide bits, don't buy the cheapos.

thanks OS. Gonna order their catalog. First try at porting heads. Got a good book and had a friend with experience show me how. Looks easy if you don't get into the valve seat and visualize the flow/impedence to flow thru the head. Looking forward to finishing my 375HP/420Ft# SBC for my 75 camper special tow rig!

Again, there is a reason why the expensive ones are expensive. You WILL be dissappointed...

That is a superb job. And the sig is a copy of haole's (eurobob's).

I have always used porting kits from http://www.goodson.com/ when I was doing cylinder head work. I tend to use mostly grinding stones and sanding cones to get much better and smoother results.

Yep, I have had great results as well (although I mostly do aluminum) with stone (varying grades) and a flex shaft on a dremel. I am talking about those 6" extensions that you can get for a dremel. They make them for air drills too I believe.

www.mcmastercarr.com has them too. Don't get to crazy about grinding out the runners. knock off the casting marks, do some boal work, and streighten out the path some but don't open them up to much or you will end up hurting the lowend power you are looking for. You probably already know that but just want to be sure.

Thanks, Dean. THat's the third time you have pimped mcmastercarr to me in as many months, I am getting a catalog already!

Thanks for the port advice. Tom J came by on sunday and did a tutorial with me. He just finished his 350 in the Willy's and it sounds awesome. I actually saw it drive tonight and everything! :beer:

(ps-should be cutting with the plasma table very soon)

Good to hear. I have all the cad files for the bender I made so sometime in the future I just might need your service.
McMaster rocks! They have everything and their prices are good and will get it to you the next day. (at least for us here in Ca)
