Header recommendations

what would be the best header for my car and motor. 71 demon 436 small block Indy top end 13.5:1 compression. Best time so far is 9.50@139. Last year I ran hooker hustlers with a 2" tube,over the winter I had the motor out so I changed to a set of tti w2 1 7/8 headers that I had and so far the times from last season to this season according to my log book are the same. Would a better set of 1 7/8 headers be better for the motor? What's your thoughts. Thanks
