Write your firing order down like this;( Lucky FE's all have same firing order)

1 5 4 2
6 3 7 8

Now when the valves on #6 cyl are 'rocking' ( ex closing/ in opening ) set the lash on # 1 valves, turn crank 1/4 turn clockwise and set #5 (#3 rocking), and so on. When you get finished on #2 the next set of 'Rocking' valves will be #1 to set #6. Use a marker pen to check off each valve after you have set it, when you have 16 marked valves your done!

Go on have a go, If you set them at the recommended lash you can never get one too tight, only too loose, and you will hear that.

On Fords numbering order is passenger side front to back 1, 2, 3, 4 on driver's side front to back 5, 6, 7, 8. Correct me if I'm incorrect.

Bob is correct see:

Sorry Bob

[Bob In Ct]

I was not giving the firing order but rather the numbering order.

Than you are correct SIR I was derailed by Jac Mac.

Brent,
I do remember that you had a problem several years ago but what was it and what was the cure? I ask because i have a new set of those and am now concerned.
Kmarccoco, I have always set mine like Jerry and Keith.
Good luck,
Byron

I should add the caution to if you are setting the lash by the firing order that you have a degreed dampner or at least marks exactly at tdc,90,ddc,270 and be exactly on the mark--The camshaft turns at half speed of the crank and will be on the base circle unless the cam is severely mis-timed.
I have never seen a cam with specs that would have any acceleration or deaceleration ramp in play at that point.

when you say "now when the valves on #6 cyl are rocking", do you mean the cyl 6 in your diagram or the actual cyl number six?

[Jac Mac]

The actual cylinder number six.

The reason I did the setting order like that is you can work your way thru lash setting in only two complete turns of the crank [1/4 turn at a time] and the cyl you are working on will be above or below the one with the valve's rocking.

Example- Set #1 with#6 rocking, Set#5 with#3 rocking, Set#4 with#7 rocking, Set#2 with#8 rocking, Set#6 with#1 rocking, Set#3 with#5 rocking, Set#7 with #4 rocking, Set#8 with#2 rocking.

All of this is easier with the plugs removed. When you bring the crank round to TDC watch the valves on cyls #1 & #6. One or the other will be in the rocking[ex closing/in opening]. If its #1 rocking turn the crank one more complete turn so that you can start your lash settings on #1. The front pulley can be marked with a piece of chalk or tape for each 1/4 turn[90deg] to help the process if you desire. I see a few guy's advocating the use of 'bump' switches. I prefer to remove the plugs & turn the crank with a ratchet& socket on the nose of the crank, or if your working on a smooth shop floor put the trans in top gear and rock the car forward to each checking point[ that may be difficult on Cobras w/o flip front ]

While JAY has the actual cyl numbers in the correct layout, he has superimposed them on a CHEV block, which staggers the bores the other way from Ford blocks. Hopefully that will only confuse the chevy owners who browse this forum looking for ideas.

I cannot take credit for that piece of artwork

Ken,
Just curious from a conversation a while back, were you able to complete a compression check and get readings on all cylinders by chance?
