Thanks for all the info are your past experiences, always appreciate hearing from folks who have hands on experience.
Brian at IMM has gone through my heads twice, second time was adding 2.055 intake valves and more porting, not sure what they flow now.
I've been looking around for used ones, but I haven't really seen anything and I don't have FB so think I might be limited in on used options. I think Newbomb Turk is a big fan of the unobtainium Hooker 5303's, so that's out of the question. If you see something please let me know!
Haven't seen any numbers, just what i gathered from reading some post. One person mentioned about them being difficult to install with a cable shifter due to the #5 pipe being in the way, but only saw one comment about that.
I had looked at them when someone mentioned them a while ago, the $1,800.00 price tag was a little to swallow thinking about how much gain I would really get. Might be something if I can't find anything else, would be nice to see a set installed.
Really appreciated everyone chiming in!
