Receiver Groove in Sleeves

How wide and how deep should a receiver groove be in the sleeves?
.
Using a .070 copper gasket .041 wire in head. .012 above head surface.

Thanks

I don't know if you are asking for peoples experiences or gasket makers specs but here goes,

According to most gasket manufacter's they recommend 75% depth of protrusion and 1.5 times the wire width. So in your case this would be .009 deep and .060 wide.

My feelings are that when you are dealing with an O-ring depth of 25% of gasket thickness (recommended maximum), particularly on a thin gasket then you might actually get the ring to distort the gasket enough to fully utilize the 75% depth rule. However in the case of a protrusion of .012 and a .070 gasket I doubt that the ring will cause the gasket to fill the void, I would be tempted to go .0075 but still maintain the .060 width. Of course I do not hold a degree in mechanical engineering nor have I done A-B testing to validate my theory, so maybe you should just use the gasket manufacturer's specs or see what others have tried.
