X-Head Porting....

DentalDart said

I'm not grinding it to anything... Just learning how to get it to have a smooth flow at the start of the port... and learn how the cast iron cuts with the different burrs and different speeds.

Also because I dont have any intake gaskets...

Your finish is getting better, as in I don’t see as many troughs. You can see the corner radius is huge. That’s because the burr or stone is so big.

Soooooooooo...I have to ask...how similar is grinding a head compared to grinding a tooth, excepting size????
