What headers for s.b stroker in Early-A

Has anybody tried these Hooker Super comp headers on their Early-A with a smallblock?http://www.summitracing.com/parts/HOK-5115-1HKR/

P.S The reason I need bigger primaries(1 3/4 0r 1 7/8)is I want full potential from the .631 lift solid roller cam.I want to see 10,s at the track!=P~
