Can anyone identify the orange things I'm seeing sitting on top my valves?

I have had a tapping sound in my in my new engine. Pulled intake and put camera into the valve areas in the heads. Anyone have any idea what that orange(?) stuff is/might be?

Gonna have to say it’s rtv. Especially see how some is missing from the gasket.

That's what I thought but I never use that color...but can that make a ticking sound in the engine....

It's from the print-o-seal intake gasket, you can see some missing from several ports.

Might make a tick/soft knock as it compresses...once had a buddy that put an engine back into service after about 10 years, had a tick. Long story short, the carbon on the piston tops expanded when it got back in service and made noise
