Compression question

Get #3 cylinder up at TDC and put air into the cylinder, listen to where the air is blowing out. If it comes out the exhaust, it's a bad exh. valve, if it comes out the intake, than intake valve, out the crankcase than hole in piston with as low as the reading is.

We had the intake off and the intake lifter of the (I believe) #3 cylinder keeper was gone and I had a bent push rod. I rotated the engine by hand and checked the valve train to make sure it was moving and all looked fine. But I did not check the compression at that time. The car is back firing out the carburetor. I will fill the cylinder with air tomorrow and let you know.

I know #3 is my biggest concern but how about #6 it seems very low also.
