Headstuds So long story short I dropped a piece of metal down my injector port and am sure it’s in a cylinder head. Therefor will need new headstuds when taking the heads off. I see that ARP 234-4336 and 234-4036 are out of stock, can’t find them. Some guy is selling ARP 234-4301 headstuds and says they will work. Before I spend half a G note is what he’s saying true? Need them asap, thanks.

No. ARP fasteners are not TTY (torque to yield). Loosen, remove head, reinstall according to ARP specs.
Just remove the intake. No need to remove head unless it got past valve an on to piston. Otherwise it may be sitting on top of the valve.
EDIT: as a matter of fact, No GM engine was TTY until the LS. So even if they were stock bolts, you just reseal threads with a sealant and torque away.
