Kevko M302 With Hedman 78050 headers?

Curious about the crank scraper in the M302 pan...by my understanding a scraper needs to be very close to the crank to function correctly. I have a 4" crank, how can it work correctly for a 3.58 stroke and a 4.00 stroke? Do you adjust the scraper on your engines and if so how do you set the clearance?

I just bought a new Kevko pan for my stroker, so I'm curious about this. No one has ever mentioned adjusting or clearancing the scraper for a stroker. It was my understanding that the scraper DIDN'T have very close tolerances to the crankshaft, that it basically just cuts off the extra oil that is flung up by the crank. I have the Kevko instructions right in front of me and it doesn't even mention the scraper?!?

I'm sure someone more knowledgeable will chime in and set us straight. Here is a picture of the crank scraper while we wait.
