Pitted/worn valve adjusting screws

Ok so looks like sarge (you da man) was right about my noisy valves...several of the adjusting screws are worn/pitted. Here is what they look like...

Imagine a lollipop.....my wear pattern look like one with a wide stick (or I guess you could say looks like a light bulb)....and a few of them have a pit right where the head of the lollipop meets the stick....Is this a normal wear pattern and is this the reason I get the "ticky" valves when the engine is at operating temp?

Also noticed when I ran the engine with the valve cover off that the 4 valves towards the rear get LOTS of oil....the 4 towards the front get very little. Is that normal? the engine is slightly lower to the rear so I can see this to a point.....

Cam surfaces look ok on all 8 valves....not pitted or burnt.

Re: Pitted/worn valve adjusting screws

Petro or Hawks . As long as they are all getting properly oiled , no worries . If the screws are worn that bad, replace them for sure . BTW, may want to mic out the rockers and shafts as well, they do wear and can create a noisy valvetrain . Just be prepared as the entire assembly is over $200 ....
