Help! 09 Taco 2TRFE timing chain/cam alignment

So I'm in the midst of reassembling my 2.7L in my 09 Taco after doing the head gasket but I'm now a bit stuck. I've been using the field service manual as a guide although in many instances it seems not so helpful.

I set #1 cyl at TDC of compression stroke w/the balancer mark at 0 before disassembly. the timing marks all lined up. Now that I'm reinstalling, I seem to be having a bugger of a time sync'ing the cam timing marks up with the crank. In order to have the marks on the cam gears line up with the casting marks on the first cam bearing cap, you need to rotate both cams a bit, the problem is, the pressure from the valve spring causes the cam to snap back to the default installation position where the marks are to longer aligned. it's almost like I need to simultaneously take 2 rathcets and rotate both cams inboard and drop the chain on.

This is a balancing act and it really says nothing about it in the FSM (unless I missed it, which is entirely possible). Am I missing an easier way to do this? When I removed the chain, the cams sprung a bit in the same manner so I felt like I knew this would be a struggle. I did mark everything before I took it apart:

 

I'm removing my cams to replace some lash adjusters and the field service manual sucks.

 

So I've had it back together about 4,000 miles now and seemingly no issues. I replaced the chain and both tensioners while I was in there.

Made sure #1 is at TDC.....I slid the timing cover and balancer pully on to verify the marks and removed it again.

I think what I ended up doing was something similar to what BassAckwards said. I used 2 longer handled ratchets with the chain in place on the exhaust side, then rotated them inboard and was able to squeeze and hold them together with my left hand where the handles crossed and finagle the chain onto the intake side with both sprocket timing marks lined up with the dimples cast into the cam caps using my right hand.

Some things I learned:

-The manual was useless for anything other than exploded parts views (even some of those are wrong & don't show you all the o-rings required on the timing cover) and torque specs. It mentions nothing about this.

-Before removing the chain during disassembly, the manual tells you to turn the motor over and line up the orange chain links with the marks on the cam sprockets and the yellow link with the dot on the crank. Besides being virtually impossible, it's also useless. I stopped wasting time trying to do this and just put #1 @ TDC on comp stroke, ensured the cam sprockets lined up with the caps & took it apart. You can use the colored links as reference when assembling, but the only time they ever lined up was probably the day the motor was assembled.

-It made me appreciate the pushrod & lifter 455 in my '69 Olds that much more.

 

Thanks for the above info. I'm attempting to replace the 2TR-FE chain, tensioners and guides and also see that I can't get marks to line up with #1 @ TDC, putting me at a stopping point worried I'll screw this up.. Logically, if you know you are at #1 TDC, it shouldn't matter, as long as links/marks are lined up during assembly makes sense...
