I would not install the cams until the head is properly torqued down. The stress from torquing the cams could affect if the heads get torqued properly. I would install and torque the cams only after the heads are torqued and all of the timing marks are in their correct positions
Has to be the problem because I don't think timing is my issue I think it is the heads properly sealing .my compression in each cylinder is all over the place ..is it really possible that installing the cams first is warping my head's and do I need to have them machined now..I only torqued the cams at 8 ftlbs I beleive is correct
And in sequence ...
