I am installing my headers and ORY tomarrow. Are they any tips that you have to make this easier? Precautions? Is thread lock needed? Do they go in from the top or bottom? Thanks a lot!

I would avoid thread lock, what happens when/if you need to take them off? I always use anti-seize for that stuff. I haven't done Macs before, but if they are like Bassani (also a midlength design) then they go in from the bottom easier, IMO.

Also, tighten the header bolts from the inside (middle bolt) out, semi-tight on the first pass (11 lb/ft or so) and tight on the second pass (18 lb/ft or so).
