Haven't found any places that make o-ring head gaskets. Wanting to make 800hp ?crank) with a 100 shot.
Need to source, 7m copper head gasket with o-rings

Not enough room between cylinders to do o-rings correctly on a 7M, Copper is fine for an engine that will see regular teardown's/inspection anything else it's a WOTAM, why reinvent the wheel a correctly prepped head/block and a quality MHG clamped with ARP hardware easily meets your goals.
I've seen a couple high hp 7m supras with o rings that's why. Figured I'd spend the extra money and do it now while it's all ripped apart then to do it after it's all together.
Up to you, personally I think it's a waste of time/effort/money.
I really don't think there is enough room between the cylinders to do it, I've ran o-rings in quite a few other engines the 7m layout just isn't one I'd try it with.
Ask SupraRich what HG he specced for Gary's 1400 hp 7M in Malta.

Personally I wouldn't do this. I went that route-copper head gasket, O ringed W/ ARP head studs and it lasted about 600 miles before the BHG. That prompted the total rebuild that I'm still working on. I would take IJ's advice and use a HKS 2MM stopper HG and be happy that I did.
