It just looks like that in the photos .. Cutters are more based for hemi head cutters are 007 and r023 .. Should have done the valve job first then blended them there were heavy pitting in the seats plus the top and bottom cut had a hard time finding a home cause of the porting and the cutters being for a porsche style head.
