helpp c20xe starting problems

[L3W15c20xe]

I've just finished doing the head gasket on my redtop nova and now it wont start I've had tryed new leads and plugs and it still wont start feels like it sparks a once and then gives up, :confused: i thought maybe the timing is out, i haven't connected the lamba sensor yet either could this have anything to do with it? Also when i took the old plugs out they we're drenched in petrol.

please help loosin my rag over it lol :tard:
