So I started these projects and got down to replacing the springs and valve locks and my number 1 and 2 cylinder can't keep enough air behind the valve to keep it up. All the other cylinders are fine with very little leak by. Now I'm in to pulling the heads off the car and hoping there isn't anything wrong with the piston bore or piston while I'm in there.

Yes, I am putting air through the spark plug and it is coming out the runners in the head. Would that be the intake valve leaking?

Use a small amount of soapy water around the valves. It will help you find which valve and where it'* coming from. I suspect a valve seal and if that'* it, you don't need to pull the head to replace it.

while the compressed air is running through the spark plug hole? So using it as like a leak detector? Sorry, I'm not that knowledgeable on cars. How do you manually bring it to top dead center, and how will i know? Thank you for your help by the way.

You need to put a wrench and a long bar on the crank bolt and turn the crank until you hit TDC on the piston you are checking. You can verify as close to possible that you are at TDC, when the intake valve closes for that cylinder.
