Piston positions at TDC

Im rebuilding a 1.8 dx engine and I am away to refit the cylinder head. The engine has had a full strip down and rebuild.
Could somebody please tell me where the pistons should be sitting at tdc.
I believe 1 & 4 should be at top of the bores but I am not sure.

Correct

Cheers, and am I correct in thinking that the rotor arm should be pointing at number 1?

Again that's right,but fitting the dizzy is best done last after the engine is in just in case you bash it
