408 stroker header size

I went with TTI step headers on my 408 build. Nice fit and finish. Worth every penny. They are flowing into 3" pipe with a Dr. Gas X pipe and custom free flowing mufflers. No tail pipes...yet.
Thanks Guys! and Happy New Year! I have been looking online at the TTI 340AW2s, And have a few more questions: Will they fit with a Moroso oil pan and can the starter be taken in and out ok with the headers in? What oil filter are you using, can I use a shorty? I have had 90 degree adapters for years and they always seem to leak. Would be great to get away from it. PS Congrats Locomotion on your Championship!!!
