if you dont want to go fast then put 3 tube headers on,,or just use manifolds..i know im going to order a set of the round port headers from maddog, since my old headers are getting pretty thin..but when i was moving up in engines and hp we compared 3 tubes vs 4 tubes on kres dyno, and saw a easy 30 hp increase with 4tubes and not using 2 inch hookers, and this was on a 11sec motor this was just using a set of 3,s vs regular 4tubes..and if you dont want to spend the money(which i would rather do)66-67 gto 4 tube headers from hedman can be put on with alittle work,,
