Thanks, Gary in N.Y.

P.S. This has been an ongoing issue with many of the aftermarket alum heads! We actually make our own "spacers" (photo below) to correct the plug depths!
Im just now figuring out this problem....Offy heads...cant get the right plugs. I see your spacers. If I need a 5/8 reach and I am using 3/4 plugs, it seems I need spacers that are .125. Is that what yours are? If so, how do I get a set? Thanks
