#4.6 FLYCUT PISTONS ARCHIVE#

Also, use an old head gasket when cutting the new pockets, this assures you get an accurate depth and don't accidently go too deep by mistake. When you go to cut the pocket with the piston in the block, take some masking tape and tape around the edge of the bore and piston. Always buy the cutter at least 1/8' larger than your valve.

There is a cutter similar to the one mentioned above made by Lindy tools and sells for about the same price as the Isky tool ($125). If you have to cut a pocket in the piston that is over 50% of the valve face (1/2 of the face of the valve), then according to Isky's catalog, their cutter will not work efficently (which I can vouch for this statement). It actually did a nice job.ĩ1 LX 398w street/bracket 6.88 1/8 60FT 1.44 My friend welded a piece of a file onto the head of a old valve to make cutter that enlarged the valve reliefs. ISKY is just one that makes a special fly cut valve that fits into the cylinder head in place of the regular valve and you power it with a hand drill.
