If they are definately the same - then no

Obviously it's desirable for cams / lifters to be matched in their original positions following a rebuild...

have you got the bearing caps in the right places too?

According to EPC, inlet camshaft for Y22Xe and Z22XE is 90543994, exhaust is 90544009. Not sure if there is any actual difference in the cams though....

Mark - did you definately fit the cam sprockets in the correct keyways?

Or are you 180 deg out on valve timing? This would cause it not to run!

Are there any stored codes?

Nah - the pulley positions are determined by which keyways you fit them in, nothing to do with the camshaft.
