Need valve spring recommendations for a stock 428CJ

[PeteF]

There are no adjustment nuts on the stock rockers? Not necessary with hydraulic cam? Could a worn cam lobe or the broken spring have allowed the pushrod to pop out enough to bind on the rocker and bend?

I think it must have been something like that. Because i have a broken spring, I'm inclined to thing that this happened first, then released the pressure on the pushrod, which let it jump out of it's cup in the rocker and got bent.

there is no obvious damage to the rocker from my untrained eye.

I was breaking valve springs in my 427 center oiler 10 years ago and talked to George Anderson at Gessford Machine. He had me send in the spring(s), retainer and the "spring cup". He looked it over and sent me a set of Comp springs and cups. They worked flawless until Keith Craft replaced everything when he rebuilt the engine a few years ago. Brent might help you out or call Gessford Machine. Being hydraulic rather than solid lifters should make the selection a lot easier.

This looks like a lovely valve spring compressor.

But since you've got stock rockers, this would do the trick quite nicely:

where can I get that tool? I would love to use one like this where I don't need to pull the rockers and shaft...

I can't find any online like this.

I knew you would ask that question. I have absolutely no idea where, or even if, you could find that now, but you could almost fabricate one yourself from that picture. If I had stock rockers, I would spend the time to see if I couldn't do just that, but I have big fat Erson rollers on mine.
