i just rebuilt a head and torqued it to the block in the proper sequence to 26 ft lbs and layed the cams in and torqued the cam bearing caps down to 10-11 ft lbs and pored some oil in the head and was wondering if it should be hard to turn the timing cam gear by hand with a wrench.......it turns easy untill it pushed the spings down till the lobe is about to be strait down and the valve fully open but i cant get it to go fully over and open and close valves easly just wondering if it should be as easy as turning the crank?

on a twin cam. engine (l presume the cam. belt is not fitted yet) you can not just turn over one cam at a time because the valves will hit on the other cam. also make sure the the pistons are not at TDC or the valves will hit the piston

on a single cam. engine just make sure that the pistons are not at TDC

thanks man i fiqured out the problem i had the pistons up at top dead center i thought i moved thim im going good not just got to find out where all there pulleys and stuff go.
