The hks cams have hks SR20 engraved in them from the pics i didnt see anything but if you want to make sure you can turn the crank by hand and see if the marks are on the other side, as for the glob i dont think its stock it looks like black silicone to me

Unless it might be reground cams. Check to see if there is a small Nissan symbol.

I have that same black glob of Silicone on the underside of my valvecover also. I couldn't figure out what it was for either so I left it there. It must be factory though, because my engine is totally stock.

there is a white paint mark on the intake cam, i didnt roll the engine over but looked again and say no other marks, i also measured the cam lobes the high point i got 38mm and the low i got 32mm on both intake and exhaust

The Black Glob is common on all SR valve covers.

the lobes look too aggressive for stock, but that's just a guess. :shrugs:
