Yep, re-checked my "official" MSD install instructs and it sez 89-lb-in for the final pass torque. they also recommend blue thread lock and to re-torque after the first 1,00 miles and again at 3,000. I have to admit after install I didn't look at mine for probably 10K miles when she started idle a little funny (sounded like I had a cam in it!), and sure enuff it needed tightened down a bit. I should also mention it looked fine out of the box (no excess flashing etc..) so mine is not ported.
Good luck!
