is that a home made gasket? I don't believe that much oil can get by the guides and seals unless there missing

I see that sort of thing all the time. Seals are shot for sure and likely the guides as well. If it was all coming from the gaskets, it wouldn't be puddled on the valve like that since the engine would have to be running for the gasket to leak. Indy heads are particularly known for holding a lot of oil around the valve. that can be as good as it is bad. Oil cools the springs, so if the rest of the parts are good (guides and seals) it's not generally a problem.

The gasket pulls the most oil under vacuum and it will be burnt vs pooling up like that. Its definately the guides and or seals. To me it looks likes the guides are wobbeling in the heads. The porting may of been to aggressive at the end of the guide on the aluminum part of the head that helps keep it steady. It appears in the pics that I see some seperations/gaps between the guide and the aluminum part of the guides stem. It loooks sloppy loose.

believe me the gasket was sealed tight this time. this happens after the motor is shut down.

Unrelated issues but why is the adjuster on that intake valve flush and the others have lots of thread sticking out? unless that's a short rocker adjuster somethings not right. Also the rocker shaft hold-down stud by that same rocker is way to short. You really should have a full nut of thread engagement for proper strength.

As far as oil pooling around the springs on some of these heads the valve pockets are sunken way to deep and hold way to much oil around the spring. I take a small burr and grind drainage channels toward the the center of the engine to assist in draining off some of this oil. Its almost begging to be sucked down the guide. Keep in mind too that any rocker ratio greater than 1.5 on a Mopar leads to more rapid valve guide wear. What Indy head it that?

they are 360-1s, I was going to grind some groves to drain the oil better. the adjuster is the same as the rest it's just the angle of the pic.

I would remove a couple of intake springs and make sure the spring pocket is not in the port
that will be checked also, but if were that bad it would be sucking air and running bad.

I didn't realize you had an oil pooling problem and have to agree with Dan on the valve seals. Those Teflon seals you have on there have seen better days. Teflon has "amnesia", once stretched they do not return to their original shape. As the valve rocks in the guide it opens up the seal and makes the hole oblong. This allows a free pass of oil to the guide. At this point I'd replace the seals. If you want I have a complete list on my website of 20 different Viton valve seals for any valve, guide, spring combination. Let me know if you need help with your selection

I've seen just a crack there that sucked in oil just like what you have

To me its just like Dan said... since it has oil puddling when the engine is sitting there its dribbling down past the valve seal and guides.. but it can be a crack in the spring seat area.... on mine the intake valves were dry so I think my issue was rings
