Wont start after headgasket replacment

[DSMAdrenalinePS]

I replaced the head gasket and i Lined up the timing and I still cant start. Everything is back in place and connect. I have done plenty of shit like this but never had this problem. What could it possibly be?

You need to give us more info for us to be able to help, just saying it doesn't start doesn't tell us anything. Do you have spark, fuel, and compression? Did you double check that everything is plugged in and that the plug wires are in the correct order?
