408 stroker header size

So does the Milton 7 quart fit without notching the subframe? I'm in Canada and can only seem to locate the Doug's headers here will these suffice for my motors power output? I need to call to see what oil pan options they have.
No, the Milodon pan requires small notch but fits with headers very well. The notch is extremely easy to do with zip wheel, about 1/2" by 3/4". 20170530_222056.jpg Where in Canada are you? Pro Stock in Edmonton is a dealer with VERY good pricing on TTI, my W2 step headers came from there.
