...only thing is the motor is a 94 Merc Grand Marquis 4.6. The timing procedure I have is NOT very good and after setting it up and attempting to rotate the crankshaft to verify...I get piston-to-valve contact. I need to see if anyone can get me the official timing procedure with diagrams to time this motor.

Thanks in advance...

is it a 2v or a 4v?

I know i have made the mistake of using the cam sensor ridge instead of the dot on the gear to line it up and they will not line up at all....

here is just a quick search on google.

Terms:

Before getting too far, let's be sure you understand the language used below. The following are a few terms you should understand.

#1TDC means the #1 piston, which is the front piston on the right side of the engine is at the very top of it's stroke after the exhaust stroke. There is an indicator on the crank pulley that will line up with the marker on the timing cover when the engine is at #1TDC. Fig 1, below shows the crank in this position.
Safe mode means the pistons are all below the deck, or top surface, of the engine block. This is important if you need to put the cams into the correct position while the heads are on the block. If the pistons are not in this position, there is risk of damaging valves while turning the cams.

Preparation:

The first step is to mark the various indicators with something that is easily visible. I used a gold paint pen, but a bright nail polish works just as well.

With the heads off the engine, make a mark on the crank sensor ring at 12:00 when the crank is at #1TDC, and at 12:00 when it is in safe mode. Put the engine in safe mode by turning the crank 45° counterclockwise from #1TDC. These marks leave no doubt as to what position the pistons are in when either of the marks is pointing straight up. Take your chains, fold them in half (you can look for the slightly darker links if you want) and mark the end links.

If the heads are on the engine, you can put the engine at #1TDC by rotating the crank until the pointer on the crank pulley points toward the #1TDC indicator on the timing cover (if it were in place), the keyway is at 10:30 (315°), and the mark(s) on the crank gear(s) are pointing straight downward toward 6:00 (180°).

Set the timing:

Put the engine in safe mode, adjust the cams to where they need to be according to your timing diagram (Chilton's, Haynes, Ford, or Fig 1, below), then put the engine to #1TDC. At this point, the lines on the two smaller crank gears will point to 6:00. Set the left side first. Pull the crank gear off, drop it in the chain so the marked link is lined up with the line on the gear. Put the gear back on the crank and pull the straight side of the chain tight. Wrap it over the cam gear, install the tensioner arm and tensioner (don't release the pins yet) and, using a 3/8" breaker bar, adjust the cam timing mark to line up with the other mark on the chain. The straight side of the chain must be tight when they're lined up. Make sure the other end of the chain didn't slip. If they're lined up, pull the tensioner pin. Repeat the process on the other side. If the cranks gears are in two pieces, make sure the crank gears are installed correctly with the shoulders facing each other. Once both sides are done, double check all the alignment marks to be sure everything is in the correct position. Use the balancer pulley on the crank to manually turn the engine over. Make two revolutions on the crank pulley. If you are making piston to valve contact, you won't be able to turn it over. Take it all apart and try again. If you can go all the way, you're not making piston/valve contact. Congratulations! You've set the timing and are ready to move on.
