I know it sounds shocking and wild, but in reality it isn't risking much except maybe losing a keeper. You have to do it on a bench where things are under control.
It's fast and it's fun. The Saab head with recessed valves makes it a little awkward, the idea of plastic film canisters as sleeves for the lifter bores sounds like a good one to protect them.
If you have to go rent or borrow a compressor, that's one reason to take them apart the easy way. Also, with a compressor, the keepers sometimes are pretty well stuck to the valve stem and each other and don't always come free easily even with the retainer pushed well down the valve stem.
With the hammer method, one sometimes stays in after the other pops out and as I said it can take a few blows. You don't even need to put wooden blocks under the valve heads, they seem to stay put from inertia as the spring compresses under the hammer blow. Keepers pop out, you're on to the next valve.
The deep socket traps the keepers so they really aren't flying anywhere. You do need to collect and organize everything tho.
And, I'd imagine if you have bent valves you really are kind of eager to see how bad they are, how many good ones you need to acquire, and check for any head damage. This would get you down to basics fast.
Also as well, you might find it would make sense to take the whole head to a machine shop once you had things apart. Don't need a spring compressor at all if so.
Be horrified if you want, cluck if you want, but I assure you it works. You're not whaling on anything really, just punching a spring down quick.
Some people are shocked, Rick, shocked, at the method of whacking the eye of the steering knuckle where the tie rod attaches, to pop the taper loose. Others swear by it.
I know this method, have used it, and though I'd offer it.
