Oil pooling on exhaust valve.

doogievlg said

The engine was broke in on a dyno and has at least five pulls on it. Also isn’t it a bit strange that it is only those two valves with it?

Any residual oil in the heads will run to the back when you install it and the engine is slanted back. So that may explain being around the back valves. But the oil drain holes ought to keep it from getting backed up high enough to flow over the exhaust guides and past those 2 exhaust stem seal. Edelbrocks will build up a deeper pool of oil back there. Hopefully, the oil drains back there are not blocked up for some dumb reason.

More than 2 exhaust valves ought to be closed at a given time so you would indeed expect oil elsewhere if it a general valve seal problem.

I'd start by:

• pulling a valve cover and see how much oil runs out the back corner
• make sure those 2 valves HAVE seals
• use a mirror and look into all the ports and look if there is signs of oiling down the valve stems
• check the plugs as suggested
