Where are the cam notches pointing when the engine is at 1 TDC? They need to be pointing inwards at each other.

Here more pics of engine... the piston n? 1 is on TDC..!

Your photo shows the F mark aligned, not the T. Align the T mark, then look at the 1 on the exhaust cam sprocket, it needs to be pointing at the gasket surface.
