Street hemi, 6pk pans came with 2 oil pan gaskets and a windage tray. Thus making the pan a little deeper. Also, sometimes you have to tweak, bend, and adjust the pick up tube for propper fitting issues. This is a very common thing. Remember after filling the oil pan, to check the level on the dipstick and see the level line on stick. You may have to scribe your own line when deverting away from an original matched set up.
