Copper head gaskets?

My old Triumph had them, :wave: reused them, bored them with the jugs, for new pistons. :good:

I've had a set in all summer. Pulled one head off twice and re-used it after annealing them. Cheaper than Honda. Spend time on head and block surfaces. I used permatex aviation sealant on both sides per directions.
