I'd suggest a thin/light/even swath of Permatex #1 (in the toothpaste like tube) around each side of the 8 port openings in the valley pan AND b 4 that, mocking it up to see if the port alignment is pretty much spot on & milling the intake if it isn't (plus it straightens the intake face) cause as you know it's along the bottom that the oil is being drawn in. Holler how it turns out. EDIT I agree get a blocked off valley pan & if using his thin gaskets that's an excellent idea to super glue the gaskets in place (not at the port openings as I am not sure superglue is gas resistant) in addition to (imnho) permatex #1 (or your choice of (non rtv) sealer) on the port openings. The MP/felpro paper gaskets I have seen are too poorly cut to suit me and they are thick which is OK if the intake (or head) face is milled so you have good port alignment. #1 port alignment & yes some have used pans dry sucessfully but I dont see the metal ridge being pliable enough to seal 15 in hg esp if both sides ain't milled perfectly flat. If your handy w an exacto knife cut your own and can get em dead nuts perfect.

I had good luck with using no extra gaskets or sealer on the valley pan. I just shot both sides with several good coats of the permatex copper spray, did the rtv on the pan rails. Also had to use permatex thread sealer on the intake manifold bolts because a lot of oil was getting sucked up the threads.
Looks like oil around the bolt holes.
Yeah, I'm definitely going to use thread sealer. When it was together and running there was oil running up one of the bolts and making a puddle in the intake. You can see it here...

on the thin gaskets..how much? where to order? I am waiting on a felpro pan with heat blocked off,was told to just use the copper spray and pan only for a BB intake swap have also been told just the pan dry will be fine,and is reusable as long as I keep the same intake..  kinda interested in this,I dont want the same trouble with it sucking oil

Done it this way for 35 years. Never a problem. I use HiTack aircraft sealer on all my wet bolts.

1qt/200 miles is a Lot of oil to suck buy the pan but I suppose its possible. Others disagree but I prefer to use the composition gaskets on both sides of the valley pan. I even superglue them to the pan the day before install--very anal about it, I create wood plates to clamp both sides.
What ever you do dont use RTV around the intake runners--RTV is not gasoline resistant.
You may have more than one source of oil loss.
I would say that is where most of the oil is getting in there. I like to use at least one gasket , and have a little machined off the intake , the composition gasket are .030 thick EACH .

I sent PMs to the guys that asked about the .015 gaskets, but if anyone else is interested send me a PM or email me directly at topside340@yahoo.com. We're also on Ebay, seller name topside340, same as our tools. Made them for exactly this kind of deal, seal it for sure when you assemble it and no worries.

this is the best solution, it's a pain in the butt finding a good machine shop that can take 0.025" or 0.030" off each side but then you can add a gasket to the valley pan without messing up the alignment of the ports and creating this aggravating problem. anyone know if other v8's have this problem or is it just mopar big blocks? why is it so common with our engines?

I test fit the intake with two of the .030 gaskets on each side(but without the pan because I don't have one yet...picking it up later) and I could run all the bolts in with no problem. It may be a little tight with the pan, but as it is now I can still move the intake up and down a little (maybe .040-.050) with all the bolts threaded in.
Well now you know why it's leaking , you shouldn't be able to do that with that much gasket in there , clean it up , all 4 gaskets and the pan and you should be good to go, clean out as much of the oil as possible, intake valves closed of course.

The sealer probally dried and cracked.Thats why I always install my pan dry.Ive run them like that for 40 years and never had any leaks.I even run aluminum intake steel heads and aluminum heads and intake that way.As long as the heads and intake are clean and flat they seal.Back in the 60s we reused the pans all the time.They were expensive then at like 25 bucks a pop.Just some silicone at the 4 corners and under the hold downs.Rocky

Sounds like the bolts might have been holding the intake off of the head
Aha, yes. That makes sense because I put the intake on without the gaskets and looked in the bolt holes and they didn't line up.

It's simple math. Angles change as blocks are decked,heads are milled and who knows if someone didn't already cut the intake...
