I’m waiting on the arrival of the new head gasket.
does anyone know what the best “scuffing” methodology approach is for the block side of the preparation, I’m using decent sandpaper about 150 grit or so.
should it be scuffed all in one direction?
or circular using the piston center as the basis?
or some sort of random?
or scuffed in arrays.. like spokes of a wagon wheel?
see pics of the block attached.
