Default Re: Head porting tools for GX390/Predator420

Pics of my 5 carbide cutters plus the 2 tool steel units I use for head porting.I lag bolt the head to a block of wood that is clamped to a table for the heavy material removal such as the valve pockets.It is also mounted this way when I use the tool steel rotary file for the valve unshrouding.
