Poly seals don't like coarse serrations either. You get poly-rubber dust as the serrations grind away the seal. You don't notice until the seal starts leaking and you pull the pan for repair.
Please check your aftermarket cranks to see if the serrations are as smooth as a stocker.

This. It depends on the crank you are using. Some even polish the crank's serrations beforehand to avoid these issues.

I've used the rope seal that comes with the FelPro kits great results. It just takes time to do it 'right'.

Neoprene seals, polish the crank. Since it's not an issue with any clearance per-se, you can use a piece of strip sandpaper to work it.
