What specs there are you'd probably find by purchasing from PPG copies of the original factory blue prints, assuming they are in the collection.

All of the valve jobs I've done over many years are on the in-line Packard engines; unless one is broken or obviously bad I don't replace the original valve springs. Though it might be nice to have another source of repro springs, I can't say I have heard of failures of the current repro springs on the market. It would be nice to hear what Ross has to say, he may have more current experience than I do.
