Timing question on 97 626
 

I had the head on my 626 off and did a valve job, put it all back together but now can't get the timing set correctly. This has me stumped and am hoping for some help.
It looks like my problem may be in the intake cam as it is hard to turn, I took the cam back off to make sure one of the lifters was not damaged but all look ok. One of the lifters though does not push as far down as the one next to it so now I am wondering if something was not done correctly when the springs were installed for that cylinder. Shouldn't the spings compress the same amount for both that are together? All the others seem to be the same. The exhaust cam turns smoothly unlike the intake cam.

Please let me know what you think..

Thanks, Kerwin
