Frame or chassis options for A bodies

My car has a spool k with TTI headers , at first I tried some 1.18" bars and it looked like it was going to take a good bit of hammer time, I had some old Mopar 1.14s on hand and they touch but not enough to have to really start beating the headers. Keep in mind these are 15 year old TTIs so they may have changed them a bit by now.
Next set I buy will be the shorty ones for sure.
