Keeps hydrolocking

Just as the title says the motor keeps hydro locking with fuel and oil. I've revealed the injectors and it keeps happening. I'm thinking about shotguning a set of injecotrs to see what happens.

Any suggestions before I do

It only takes one cylinder to lock up the whole engine. Find that cylinder and repair the problem. Save your self some time and money.

Couple things come to mind. Old copper washer still seated in cup. Cracked cup. Dirt/oil in bolt holes for clamp downs preventing proper torque of bolts. Stuck open injector needle valve.

I have more than 1 cylinder that's doing it. I poked at one of the cups that hydrolock ed and it looked fine with no seals in it. I have another cylinder that's doing it. Before this I had my ipr valve get stuck open due to the hpop screen getting demolished. So I'm thinking part of the screen getting lodged in the injector making it stick open. Is this possible?

No, that would only cause a problem on the oil side of the injector. You would need a broken tip or a seal problem to let fuel, or possibly oil, into the cylinder. You could also have a cracked head that leaks when the engine is off. If the injector cup was cracked, you would get water in the cylinder when the engine is off, or possibly water in the fuel that could damage the nozzles on restarting.

Im thinking improper hold down or sealing of the injectors. Since injectors are expensive, I would replace the hold downs, and reseal the injectors again. Label the injectors on cylinders that are hydrolocking, and move them to a dry cylinder. If the issue follows the injector(s), replace the faulty ones.
