Yes, that is a bit heavy and likely squeezed out a significant amount.  The stuff that oozed out does not provide any seal - you can cut it off and make the appearance better.  I use Suzukibond on black engines and Hondabond4 on silver engines......when the color matches it blends in better and is not so noticeable.

A thin bead is all you need.

The lobes on your cam appear dry - I applied a cam lube with moly grease to provide lubrication at start up.  Be sure that you fill the tray under the cam with oil before you start the engine - you can fill it from the exhaust valve inspection port once you have the engine back in the frame.

I have used a tiny brush to apply a small amount and then come back and spread/thin it a bit more.  I like the syringe method though and plan to use that if I ever need to repeat the process.

To be honest I didn’t know how much rtv to put and didn’t want to put too little and have it leak
I read a post and someone wrote to make the bead the size of a pencil, it looks fine, not much ozzed outside so inside must look the same.

I removed all the excess around the outside and removed what I could remove inside the valve covers.
I think it looks good.

Hope all is fine, I’ll keep y’all updated

A freshly sharpened pencil or a dull pencil?  A regular pencil or a jumbo pencil?  

How about a 2mm wide bead?  Is 3mm too fat?  

Having recently done this, my OCD went through the roof...      I had about a 1mm oooz of extra unneeded RTV squeezed out on the outside when I was done (so probably about the same amount on the trouble-maker inside that you can't see as Gary in NJ noted).  For a rookie, not bad IMO.  We'll see what the dissected oil filter says in a couple months.
