More Timing Questions

[Pope1]

Guys, I'm still trying to get to the bottom of the timing issues on my car. I'm now wondering whether I should take the timing belt off and either re-align the two cams relative to the crank or vice versa. Really need some advice please as I am not sure what to do, if anything. Here is the situation.

If I align the two cam wheels with their pointers like this

then the crank looks like this

However, I am 99.9% sure that mark 3 is TDC, not mark 1. If I align mark 3 with the pointer like this

then the cam wheels look like this

What would you recommend?

1) Leave the thing alone, unless you really like fiddling.
2) Position the cam wheels as in the first photo, take belt off and rotate crank to line up with pointer, refit belt and re-tension.
3. Position the crank as in photo 3, take belt off, rotate both cam wheels to match photo 1, refit belt and re-tension.

If the answer is 2, can I rotate the crank that small amount without rotating the ancillary pulley too?
