1999 s80 timing off

Put up some resistance or came to a dead stop?

Are spark plugs out? Could just be compression resistance and the weight of 6 cylinders

no, the plugs and cop's are removed. dead stop. not resistance

How closely are you adhering to the Vida procedure I attached?

The only thing I can think of now is bad crank referencing and/or bad cam referencing or more bent valves.

When you pulled the head off were valves seated in their seats or were there gaps. A simple test is to fill the combustion chamber with gas/fuel and test for leaks.

i just received the head back froim the machine shop. i did a light test to make sure they were all seated. i will go back over the Vida procedure.

AZ,

When you are indexing the cams, are you setting the slots horizontal such that the intake cam slot is slightly above center and the exhaust slot is slightly below center?

yes, it is exactly like the picture you sent me. it is a straight camlock so i may be off ever so slightly, but i am giving it another shot. the only valve going down in question is #3 on intake. but the piston is going down, so i don't think it is a problem.

it must be in the VVT. but if the cams line up and the vvt is clockwise as far as possible and mark is right then it should be in relative timing, correct?
