And that's after positively knowing the piston was at TDC (by using a McDonalds straw to stab into the spark plug hole, crushing the straw between the piston and quench area). Maybe it was because the springs I have done had a tall install height. Dunno. I've only done one set of stock springs and I ran into the same problem.
The rope trick is a quick, dirty way to know the piston is close enough at TDC to use the compressor and it's nice to have a bit of a cushon for the valves if you have to tap on the compressor to get the retainer off the keepers.

the part about the rope.

Go to hardware store and buy some 1/4" nylon rope. Stuff rope into clyinders through the spark plug hole. I usually get about 2' in a cylinder depending on where the piston is. Turn engine over using socket wrench on crank bolt until it stops. Make sure to keep rope clean when doing this so no foreign objects end up in the cylinders and spark plug hole threads. DO NOT back off piston until both springs are on the valves. Turn engine over in reverse fashion and pull rope out of spark plug hole. Repeat.

Re: Valve spring replacement?

I never used rope, but that does seem like it would be pretty simple to do it that way.

I still dont know how crazy I would be though about having that in the cylinder... It would be so easy to get a piece of dirt/sand something that shouldnt be there, in there.
