From: Who says "Nothing is impossible" ? I've been doing nothing for years.
The new AFR 227cc Eliminators I have the oil pools up at the back-end where the drain-back hole is enough so it goes over the "wall" of the head and into the gasket which has to be RTV'ed there at the back or they will leak.
Never had this problem with any other Perfromance head as the oil never got high enough back there that you could run them with no gasket which is almost exactly what I did with Vic Jr heads, put the valve cover on and didn't put the bolts in, so there was actually nothing holding the valve covers on. Came back after a short drive and was astonished that despite the mistake I made no oil ran out of valve covers
*I put this on all my posts: Please post back to those who helped you, the final outcome of your initial post

Ever since day one, my 383 has used a quart every 1000 miles. I drive it very hard, and expect this. Every engine I have ever built has done this and the quart every 1000 is not much in my opinion and has never cause me issues and 30 years of building hot rods. The AFR195's are a new addition to this engine which now has 25,000 miles on it. With the new heads, the amount of consumption has not changed at all.
In addition, I gained 35 horsepower on the dyno, from the numbers I got using the cast iron heads that I had ported and polished when I first built the motor.

I installled the 210 RRs about 7 years ago and had a problem with the oil pooling on top. I took the heads to a machine shop and had them mill a groove front to back as well as increase the drain hole szie some. Put them back on and haven't had a problem since.
This was a fairly common problem back then, I believe the addressed it with their new style heads

My older 195s have the valve cover leak problem Motorhead talks about.
I went ahead and cut a drain trough at the aft corner edge so it has no where to pool. Now no valve cover leaks anymore.
I also opened up the fore and aft main oil drain holes to help decrease pooling around the whole head.
I burn a quart every 500 miles but not sure it's the heads.

Ok guys,this is a old post but after redoing my engine because of burning oil,i think i found the problem,it was my high volume oil pump,it must have been flooding out my heads and being pushed in the valve seals and guides.I put in a new crank and regular pressure oil pump and bearings and rings. the heads were wet on top of the valves which told me the oil was coming in through the guides and seals.So the answer was so easy ,a regular pressure oil pump did the trick.I was running like 80 100 psi when cold ,then once warmed up 60 70 psi.plus high volume on top of it.So if somebody is having oil burning with new rebuilt engine,it could be the oil pump.i dont think i will ever run a high volume oil ever again on the street.

So I'm curios how one determines when they have a Oil Pooling problem. I have AFR 180's and they are about 6 or so years old. I use a High Volume pump as my Engine is Turbocharged and they need Oil to. I have had an issue with the Oil getting sucked down the PCV Valve. My Valve covers have no baffle for the PCV. I have recently switched the PCV from the aft right side to the forward left side and it seems to be working better. However now I am getting Oil coming out the Breather that is now back on the right side.
