how do you guys make sure the valve stays up when swapping valvesprings?
I have read the ls1how to writeup as well as watched the video. I have swapped 4 springs out so far by having my air compressor running into my sparkplug hole with a compression test kit at 60-100 psi. but on the last spring i was compressing the valve dropped about halfway down. so i grabbed the crankshaft pulley and quickly turned it over.. i was able to pull it all the way up but there has got to be a full proof way to make sure the valve wont drop into the cylinder. any advice is appreciated!!

Find TDC in each cylinder and do it. Quickest way is put a straw in the spark plug hole and rotate the crankshaft until you see the straw go up and down and stop about where the straw is at its highest point (TDC). This will keep the valve from falling too far into the cylinder....you wont lose a valve this way.

Make sure the intake and exhaust valve you are swapping the springs on are closed. Pull the valve core from your compression tester, disconnect the gauge, screw it in the spark plug hole and connect the house air to it. It will keep the valves up while you swap the springs. If you hear lots of rushing air then one of the valves are still open.

This is how I do it too!

Exactly how I do it!

after you air up a cylinder...and begin to compress the spring... tap them with a hammer to free them up
the only way they will open the valve is if they stick to the retainers and top of the valve
tapping them firmly with a hammer (enough to get a nice popping noise from the air rushing out of the valve) will keep them from ever having an issue with compressed air.

if you hit it hard enough to damage a valve...then you were hitting WAY too hard in the first place...
a small ball peen will do the trick...
if you are really worried about it...coat the hammer with some Plastidip first
