if its not turning over with the cams out of the head (not just loose, bearing caps must be completely off and chain removed from cam) then you have a bigger issue, and quite often its a faulty manufactured head gasket hitting a piston or something with the chain (like a joining link hitting something, seen them put in with the clips on the rear side causing them to hit casting ridges as stopping the engines from turning over)
first thing is to not turn anything, if you do you will bend valves (if you haven't done so already)
Remove the chain off the cams (I usually remove the pulleys and chain from the cams as a unit) and once you have done so remove ALL the cam bearing caps to let the tension off the valves so they are all closed. You can now turn the crank (using a helper to hold the chain so it doesn't get caught or come off the pulleys) and line up the TDC mark, then set the cams in the right position, (from memory cyl 4 tdc compression cam lobes pointing up, cyl 1 should have valves "rocking" as in lobes pointing towards cyl) fit the chain to the pulleys in the right position, tighten the bearing caps to the correct torque then refit the pulleys to the cam(s). Of course you should confirm the timing marks with the manual before turning the engine over.
Gently turn the engine clockwise by hand and if there is no binding anywhere then you should be ok to do a compression test and check for bent valves. If the compressions ok, fine. If its down, then you have bent a valve and the heads coming off again.
