I was thinking about laying a copper wire in that void of those huge fire ring bore composite gaskets like you did .then it will have 2 fire rings. double protection . or better yet ask cometic to make a copper fire ring for the small bore 273 since they don't want to start a production on the proper shims. gasket.

You don’t need a cooper wire or anything like that.

If you are going to do that you use stainless wire and you cut a groove in the block and a matching groove in the head.

The wire goes into the head and the groove in the block is the receiver groove.

Plus you need dead soft copper gaskets.

As to bolt length, you need about 1 times the diameter of the bolt of thread engagement.

I doubt bolt length is an issue. If it was you’d be pulling the threads out of the block.
