Notes from SCE:
If you go with double o-rings they should not be stacked unless you use a thicker head gasket. Since copper (like a liquid) does not compress, rather it is displaced, the gasket does not like more than 25% of the cross section impinging at any one spot. Over 25% of cross section you risk cutting the gasket. I suggest off-setting the o-rings so as to deform the head gasket into an ”S” shape between the rings. Off-setting in this fashion will most likely require that the o-rings in either the head or block are in a ‘figure 8’ pattern but you will have to do the layout on the actual deck surfaces to be sure.

Glad to see its moving forward.
I think my double orings are offset .012" but I didnt do the figure 8 method. Did you buy a custom diameter gasket or the 4.380 standard they sell? The first set I bought pushed the inner diamter of the gasket really close to the bore. I would say it was less than .015". The final 3 sets I bought ended up being the 4.380 bore which I liked much better.
Keep us posted, we wanna see it run as much as you do.
