    Singh grooves won't hurt; not sure they help but some porters subscribe. Claims are that the grooves will reduce the potential for detonation in high compression configurations; better flame travel. You can do it yourself with a dremel tool or a triangular file. Size and location is not critical; just have to keep the grooves from encroaching into the gasket area.

    So if I were to do this I would put the head gasket down on the head , use a sharpie and trace the inside of the gasket . Then I would have a go no go section marked off ?

    And bigger is not better for Singh grooves. Dolt's pic gives a good estimate. Google Singh Grooves. Photo's will have you double triple guessing what to do.
