Big tube header vs small tube header on a stroker

I have a set of 1 7/8 Hedman headers on my 408 & they are hands down much better than the 1 5/8 tube junk I had on it before. I bought a set of 2" tube headers from a member here a while back & I'm going to run them on my 416 when I finally get it built. But keep in mind, my car is race only & will never see the streets.
