With the crank mark pointing up and the cam's down, #4 should be at TDC compression and #1 will be at TDC exhaust.

Valve damage *can* occur on these when the chain breaks. Since you have the timing chain installed correctly, you're likely looking at some valve train damage.

I agree, as with direct ignition systems it shouldn't matter whether cyl 1 or 4 is on the compression stroke because they both get a spark regardless. This is important on an engine with a distributor.
