Re: Restoring Rusty
we will be testing the heads to see if they are warped or if the surface is true in three different ways
1. use a metal straight edge and once again our trusty handy dandy flashlight, turn off some lights in your state of the art facility and see if the light of the flashlight will shine through underneath the strait edge while holding it flat on the cylinder head (this is not a perfect science) also not ideal in all areas of the surface only the ones solid underneath
