Nothing like a spirited discussion! ;-)
I found this article on another page.. just dont understand the cam holding tools part, the forddvd does not mention those tools

Removal
CAUTION: Since the engine is not free-wheeling, the timing procedures must be followed exactly or piston and valve damage can occur.
Remove the engine front cover.
Remove the crankshaft sensor ring from the crankshaft.
CAUTION: Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur. Position the crankshaft with the keyway at the 12 o'clock position.
Install and fully tighten the special tools on both camshafts.
Remove the timing chain tensioning system from both timing chains.
1 Remove the bolts.
2 Remove the timing chain tensioners.
3 Remove the timing chain tensioner arms.
CAUTION: Unless otherwise instructed, at no time when the timing chains are removed and the cylinders heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur. Remove the RH and LH timing chains and the crankshaft sprocket.
Remove the RH timing chain from the camshaft sprocket.
Remove the RH timing chain from the crankshaft sprocket.
Remove the LH timing chain from the camshaft sprocket.
Remove the LH timing chain and crankshaft sprocket.
Remove both timing chain guides.
Remove the bolts.
Remove both timing chain guides.
Installation
CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result. Compress the tensioner plunger, using a vise.
Install a retaining clip on the tensioner to hold the plunger in during installation.
Remove the tensioner from the vise.
If the copper links are not visible, mark two links on one end and one link on the other end, and use as timing marks.
Install the timing chain guides.
CAUTION: Do not turn the engine over with the Camshaft Alignment Set or damage to the camshaft sprocket or the bolt can occur. Install the special tool.
NOTE: Slightly loosen the Camshaft Position Aligner tools to allow slight camshaft movement. Pre-position the camshafts.
1 Rotate the LH camshaft with the Camshaft Alignment Set until the timing mark is approximately at 12 o'clock.
2 Rotate the RH camshaft with the Camshaft Alignment Set until the timing mark is approximately at 11 o'clock.
Tighten the Camshaft Position Aligner tools to maintain camshaft pre-positioning.
CAUTION: Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur. CAUTION: Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur. NOTE: The number one cylinder is at Top Dead Center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool. Position the crankshaft so the number one cylinder is at TDC with the special tool.
Remove the Crankshaft Holding Tool.
Install the crankshaft sprocket, making sure the flange faces forward.
Position the lower end of the LH (inner) timing chain on the crankshaft sprocket, aligning the timing mark on the outer flange of the crankshaft sprocket with the single copper (marked) link on the chain.
NOTE: Make sure the upper half of the timing chain is below the tensioner arm dowel. NOTE: If necessary, use the Camshaft Alignment Set to adjust the camshaft sprocket slightly to obtain timing mark alignment. Position the timing chain on the camshaft sprocket with the camshaft sprocket timing mark positioned between the two copper (marked) chain links.
NOTE: The LH timing chain tensioner arm has a bump near the dowel hole, for identification. Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner.
Remove the retaining clip from the LH timing chain tensioner.
NOTE: The lower half of the timing chain must be positioned above the tensioner arm dowel. Position the lower end of the RH (outer) timing chain on the crankshaft sprocket, aligning the timing mark on the sprocket with the single copper (marked) link on the timing chain.
NOTE: If necessary, use the Camshaft Alignment Set to adjust the camshaft sprocket slightly to obtain timing mark alignment. Position the RH timing chain on the camshaft sprocket. Make sure the camshaft sprocket timing mark is positioned between the two copper (marked) chain links.
Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner.
Remove the retaining clip from the RH timing chain tensioner.
Remove the special tool.
As a post-check, verify correct alignment of all timing marks.
Remove the special tool.
Position the crankshaft sensor ring on the crankshaft.
Install the engine front cover.

The cam tools bolt to the heads and gear in with the teeth on the cam phaser to stop the cam from moving, but for this job, I really think it's a pointless tool. The valve springs put a LOT of combined pressure on the camshafts, by their very nature, so as soon as you remove that tool, the camshaft is naturally just going to snap to wherever the valve spring pressure puts them. That's where the vise-grips come in handy. Snap them onto a spot on the camshaft where there are no lobes, and then you can rotate the camshaft one way or the other to line the phaser up with the marked chain links.
I don't remember if you said you were going to do lifters and lash adjusters or not, but if you are, you have to take the camshafts completely out anyway, so you can just lay them back in properly when you're done with that. BTW, the reason they go nuts about the diagrams showing cam position and using the clock to time things and so on are because there are some chains and kits out there without any timing marks at all and require the clock to be timed correctly.

Something that confuses me still: some articles specify removing some of the followers with valve spring compressor and removing cam caps. is this necessary? And why?? anyone???

Some articles recommend the valve spring compressor so you can take the roller rockers and lash adjusters out without removing the cam. That's so you don't have to remove the timing chain and re-time the engine. But, since you're taking the chains off to replace them anyway, there's no need to use a valve spring compressor since its whole purpose at that point is null and void with the chain removed. When you get the chain and phaser off, remove the cam caps and just lift out the whole cam and you can pull the roller rockers and lash adjusters out by hand (they're literally just sitting in there, the cam is the only thing holding them down).

Well do you want to replace them or not? I'd recommend it since you're right there...
