LSVTEC 91 Civic

Okay, heres the problem. A while ago when I installed my ITR 4-1, it rubbed on my oil pan, because of that I had to "modify" my LS oil pan to fit the header on there, ever since then it has been leaking a little bit, I think the pan is warped. I put a new gasket on yesterday, torqued down with hondabond to 9ft/lbs, and its still leaking! I've heard that PR3 oil pans will clear on my motor with my header, true?
