2.0 l, Firing Order

[Smooth Gecko]

I have just done the head up on a 2 litre motor. ( to get a miss that was in there). No 2 Ex was bent badly. Bought a new valve, lapped them all in.
Still shake rattle & roll.
Havn't got a manual and was trying to recall if this was the motor in the back of my mind with an unusual firing order ( not 1342)
Just done it, have not changed plugs or done compression test yet.
I set the clearances @ 10 & 12 thou. but it misses straight away so shouldn't be this. The proper clearances would be nice too.
