K member notching question

Ive done a lot of reading about K member notching but I’m a little confused if the notching is only nessary if the engine is installed from the top with the oil pan in place. If the K member is out of the car and I atach It to the engine defore it goes in the car will a milodon street strip 7 or 8 quart pan fit without notching the K member. I ask because I want to get the K powder coated but the engine is not done to check things. Thanks.
Without notching the k member, at least on the front pass side corner, the milodon pan will hit the k member. The trick is to cut the front pass side corner off the milodon oil pan.. about a 3" corner section...then weld a flat piece over it.
Another place hedman headers hit is on the drivers side upper middle where the sump section seams to pan..its bulged and needs a cut , hammering in a bit and then re weld it up again. See...If you modify the k member, you rid one of those 2 issues with aftermarket oil pans BUT, now you're cutting on the car ...and not many wanna cut the car. Oil pans are very replaceable...unlike 50+yr old k members .
