My oldest son has had one on his car for several years.He bought it new back when they cost $140. His had very little core shift. My middle son bought a used one off this site for his magnum. It had slightly more core shift, but not terrible.
He cleaned it up pretty easily.

Bought one for my son's valiant with a 5.9 swap. We haven't run it yet but i don't expect any issues in that regard.
My issue is the dual use provisions. it comes with plugs that we could not get to go into the unused bolt holes for the LA style heads. Probably supposed to be done with a press or something but if you don't have one... well I wasn't comfortable whacking on any harder then I was with a hammer. We're going to ream them a bit and JB weld them into place... or something...

If you don't have a press try a C-clamp. A good one. not a pot metal one.

Ours had HUGE core shift. ports would not line up using the LA bolt holes.
hope to try it with the Magnum holes in a future project.

Toss the plugs in the freezer overnight and try again

Just so we don't get on a tangent about our manifold, i should have said, we already went down the stated path, but haven't epoxied the plugs in yet. Holes are reamed and the intake is installed.
The suggestions are appreciated though.
Now back to our regularly scheduled program

Good.. didn't know it was a dual fit and comes with plugs for extra holes.
Intended use here is for a 340.
Thanks
That is concerning for sure. So you bolted it on a LA and the ports don't line up properly?
How you see the offset at the ports?, can't really look down the runners on a dual plane.

Put an Eddy Airgap on it and it fits and functions perfectly.
You get what you pay for. Pay for ****. Get ****.

I know I'm right....
I had an Edel Air-Gap that was that bad but it was S shaped! Sat a Crosswind next to it and it was laser straight. I heard The Crosswind wasn't sand cast but made from permanent steel molds but from a manufacturing process student looks impossible to do 100%, maybe the ports only?

I have both and they all need port match work to get them right. If you order from Summit and the core shift is so bad you can send it back for another.
Well, the two I have had here were better than my edelbrock. None were even close to what moparpirates looks like.
My oldest son's is on eddy LA heads, my middle son's is going on Mag RT heads

Ours was on EQ's.
Put an old Eddy 318/360 intake on as a test, it lined up perfectly, but killed the performance.

If the coreshift is bad enough that it is super obvious using the gasket as a template ... guess it's pretty bad.

No other that I've seen have the rear water ports .... or cast pads to drill and tap.
That would be 'some good ****' to add to the name brands.
So I guess now we even have to manipulate new intakes to make them right. It's all up to us. If we stop accepting shoddy work, they'll have no choice but to improve.
30 years ago, when you bought Edelbrock, Weiand, Offenhauser and any other name brand intake, this kind of thing was the exception and not the norm. A shame, really.
Oh my !

I just went to the spare bedroom to look at my Offenhauser Port-O-Sonic intake for my 351C Ford. It's a total badass intake with the 4V sized intake ports. They are perfectly in line, no excess casting flash, just a beautiful casting. Also, possibly one of the best intakes ever made for the Cleveland perhaps only eclipsed by the Strip Dominator. All this just makes me want to look for vintage parts all the more.

I don't think Ive ever seen a bad Offy intake. They were some of the nicest stuff out there.
Vic was way better at marketing.

Ford junk...
Yes, and ALL of the early pre-Holley owned Weiand stuff was total badassary too.
I wonder if these manufactures ever read these forums.... 
I asked Johnny Mac to make intakes - magnum especially. And can we get a new one for 200 or less please???
