Bent valves investigation.......

The intake and exhaust valves of cylinder #6 were replaced after a stray nut got into the cylinder causing the rocker arms to break. Anchor Atlantic did the machine work. At this point, I have to test and confirm if the valves are sticking or nut. Without the rockers installed, the crankshaft rotates without producing this peculiar noise I am observing.

The next step of the investigation as suggested earlier is to isolate the valve train and drive train which I will perform immediately. Could someone make a comment if I could remove the valve springs insitu (cam tower installed) using P7I & P7E tools? I have not done this test before so anyone with experience please chime in. Thanks.
