[QUOTE="RoadRash, post: 9649006, member: 2934"] I've been searching around and can't quite find the answer. I'm currently building a new motor (.030 over, stock rods, crank, ported heads/stock cams, ported lower). My power will probably be 650+ / 600+ range with a whipple 2.3. I am looking at Kooks and ARH long tube headers. What size primary should I choose? I have been thinking bigger is better and looking at the 1 7/8" into a 3" collector with a 3" xpipe to 2.5" bassani catback. With the 1 /7/8" primary, how large is the header flange opening? Will I need to have the shop port match the heads to the new header? [/QUOTE]
