When I need plates to be lapped, I send them to Racing Beat. They are the only ones that I know that have the propper tool to lap them. When it comes to making sure and engine is not warpped across the side housings I don't place money value on that. Is to critical for me.

Yes, A straight edge across the side housings in a cross pattern. Racing Beat is well worth the price.

My engine builder won't build an engine without lapping. He is very critical of ever tolerance. He actually built his own lapping table. I got to lap my own plates with his guidance.
