My son's 1968 Chevy

It all depends how much $$ you have for it. Do everything now and it all lasts longer.
Or save $$ and diy the studs. Taping cast iron isn’t that hard. The holes are going to keep the tap straight.

Plugging up the oil drain holes to make sure no metal shavings go down inside isn’t too bad.

I talked to my son about it and he’s onboard with sending the head to the machine shop for the repair. Also to pull the engine out and inspect everything else. I’m not too familiar with these engines to know weather or not having three dead pistons slinging around would cause any damage.

I know some will some won’t. Having it out on a stand will make things easier to work with.

I'd pull that head off. The only other damage would be to the piston, readily visible then. Seems like a lot of extra work and money to pull it out if not needed

I'd be surprised if it damaged the pistons. Normally would need the valve to have fallen in
