Going to run a set of bender pipes on a 1997 700sx. Can I get by with the head gasket mod and use 91 octane fuel, best we have in Canada, or should I run with the stock head gasket? I have a tempaflow and was going to start with 155 jets. Also I've seen where it says to richen up the needle on the center cylinder, go from 3rd clip down to the 4th clip, but only on the center cylinder. Would like to hear from the guys who are presently running these pipes and what you have found.
 

yes you can, if you do everything you posted above , you will be fine. those pipes make great power on the sx with head mod. 3:16 (yammie tony)
