My stock pistons need to be notched for 2.02 valves and i was wanting to know what the best way is to do this. Will renting a tool from isky be the best way to go? Thanks for any input.
The "professional" way to do this is to buy a piston notching tool, such as the Isky Cams product shown here. The tool is simply a valve head with "teeth" on the face. This head attaches to an arbor, and is then installed in place of the valve in the cylinder head. A drill is attached to the arbor and used to turn the tool, and as a result the teeth grind the piston exactly where the valve would contact. The tool comes in various valve and guide diameters to work with basically any popular engine and head combo.
worked very nice when I used the isky cutter. But make sure you have all weekend for the cutting and checking it takes forever. isky's #323770-0930
150 for the tool is alot cheaper than havin someone else do it
