sometime this next year i'm going to get afr 165 heads and putting in an e303 cam, i'm wanting to know what kind and size headers i should get.....what i had my 92 gt was an e303 cam, ported stock heads, and mac 1-5/8 shorty equal length headers ( i'm not going to do equal length anymore, they looked awsome but they were a pain to keep bolts tight).... my brother-n-law suggest since i was going to get afr's to get 1-3/4 headers....is that correct??? i'm thinking mac 1-5/8 shorty's........help me decide.....
