Head bolts are the center 1st then the four outer then the four inner.
Most covers as Trevor said. Look at it as a clock, tighten 6,12,5,11,7,1,4,10,8,2,9,3.
Rocker box the four long bolts FL,RR,FR,RL then the bolt center inlet then front nuts then rear nuts.
At least thats how I've always done'em.
Cheers
PS. Steve, the SGC is working a treat.
