Broken Valve Spring

I've been following this thread and don't know why you just don't pull the engine. You will end up damaging the car by effing around with this in the car. You see now that you wouldn't be able to replace the head even if it was repairable with those studs, and there most likely is some other damage. Pull it and fix it the right way.

OP, this is you in spades! On two different levels.

First,

That engine is not repairable in the car. Pull the engine and fix it!

Second,

Dicking around with all this touchy feely how bad is it hurt discovery stuff is the equivalent of needing the machine and not buying it!

In the end you will not have fixed the engine, still need to fix the engine and now have to begin the process of removal and repair.

Skip all the BS, pull the engine, clean the good parts, trash the bad parts, buy replacement parts and repair your engine!

As above, do yourself a favour and take the engine out. Perhaps find an engine builder. You can do it yourself. Many others did, but do you really want to?

You might find an oddball piston, deck height, pin height, bob weight combo which will make you despair.

I'm sorry to say that I 100% agree with the other boys above. Near 40 years as a mechanic, I would not attempt V8 head stud removal in situ.

The engine will need a full rebuild, there's no doubt. Don't try and do things by halves. The damaged head might be salvageable, the BIG question is whether the block is salvageable.

So now let's get set up to pull the engine out, put it on a stand, and do an inspection diagnosis during the pull down process.
