Is this an acceptable replacement for the original GM one ( MAHLE part # GS33431 ) ?
The original GM one is part # 12581822.

Should be just fine - actual brand depends which company had the "AC Delco" supply contract when your engine was assembled.

Ok thanks Sub, just wanted to make sure I know this part is crucial so I want a good one.

Ask Jake at www.northstarperformance.com. He bought out most of the remaining engine parts auctioned off from the Livonia assembly plant for Northstar.

FelPro, Victor (Reinz), Mahle, "AC Delco", others. All just fine.

Why does the MAHLE oil distribution plate not line up with the guide pins on all 4 corners that are meant to assist with proper installation, even came with instructions saying it may not line up and to remove the alignment dowels, i should have got OEM GM.

My experience has been that the GM ones don’t line up very well either. Had to take a Dremel, elongate the holes about .01 in the lower case on both of the engines I have.

Thanks for the info, guess it would not have mattered then. You would think that a gasket as expensive as that one that they could at least manufacture it correctly!
