assuming that u still have stock cam sprockets (dont c them in ur sig). take the cam belt off (loosenin the tensioner of course). valve cover off of course. if u can hook up w/a jetter that has an alignment bar 4 the cams that would b good. or u could devise some other type of straight edge 2 get the cams close. using the bar, line the cams up that both of the keys on the back of the cams slide over the bar. with those held in place and sorted. take the spark plug outta #1 (plug nearest cam sprockets). stick a long screwdriver down into the cylinder. have a buddy/family member watch it. watch it as u take a 18mm socket and w/ratchet or breaker bar turn ur udp (crank pulley) bolt clockwise. u need 2 turn this til the screwdriver is at its highest outright pt. keep turnin til u find this u will have 2 fidget a lil 2 get that every last bit 2wards tdc on #1. with that done, u can start 2 button everythin up. belt on, bar out, cover on, tensioned, ur set. if u have adj cam sprockets and want 2 align them w/each other (aesthetics) then loosen ur cam sprocket bolts (not the adjusters, the main bolt torx 55) and move accordingly. make sure that if u doin anything w/the cam sprocket bolt that u DONT rely on the alignment bar 2 hold the cams in place, u will break them. vicegrips in between the 1st 2 journals will suffice. any questions welcome. good luck
