If the parts are in the NHRA Accepted parts list, they are deemed legal.
Also, there are many like myself, that ships their OEM or NHRA approved replacement oil pans to Stef to have them baffled and screened. It is within the parameters of the rule book.
One area that I have seen big violations is in the piston configuration such as thinner ring grooves than those shown in the spec and still the piston has the correct accepted part number.
I was discussing this subject with a well know engine builder that builds some of the fastest engines in the country and he told me that NHRA has told him that he is one of the few engine builders in the country that has pistons with the correct ring grooves and location.
