No stones... they load up way to quick... you can use toosie rolls with some stiff grit if you dont want to use the cutting bits

I'll have to experiment on an old head to see if I can get the contour I'm looking for consistently using sanding rolls. I may also try a small fine-cut, egg-shaped, carbide to see if I can get the same results w/o cutting away too much too quickly, which is my big concern.

I also have a support bearing on my longer burrs so they dont fly around the port if they bite too hard... with all the different grits on the tootsie rolls you can hog or fine tune it to be as aggressive as you want... I pick up boxes of tootsie rolls in assorted grits from the local abrasive company for alot less money.... I probably have 6-8 boxes of different grits and diameters right now

If your going to reshape the chamber to unshroud the intake and maybe the exhaust lay the head gaskets you going to use on head and mark inside them you don't want to end up with the fire ring hanging inside the chamber!

I used the heavy alum. egg shaped cutters where I was removing the most material like the p-rod pinch, roof,walls and lightly in the bowls then followed up w/the tootsie rolls for the final shape and finish. I would lay your head gasket on the heads and base my work/shaping on that as my guide.

I'm not sure if my response should be "It takes one to know one" or "I've got no room to talk." The best thing I can say about my own porting is that at least nothing I've ever ported (so far) has ever SLOWED DOWN after I worked on it.

I really enjoy porting heads and in my case they seem to have helped my et`s picking up almost two tenths and 3+ mph. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

You will feel it in your arms the next day as you with pressure decide how much and what material comes out the use rolls to finish. So if you got a good amount of work to do, its easy to feel confortable using them vs a carbide which I olny use on iron heads. They also sell an 8 inch ext. which I didnt put in the pic. Good luck either way ya do it..... 7294284-DSC03326.JPG (49 downloads)
