Thanks ps2cho and duxthe1. Great info, but not an answer to my question. Is there a sequence to follow when installing and torquing cam towers. I have installed Timeserts in ALL 24 cam tower bolt holes. Ps2cho, the pdf you refer to does Not reference cam removal and or reinstall. Duxthe1, I tend to agree with you on first bolting head to block, but I still would like to know sequence and torque values. Anyone have any info on this and pros and cons on installing cam and towers with head off block as opposed to head on block. Thanks y'all........
