The tappets are supposed to rotate slowly during operation, to even out the
lobe-tappet wear.
So it might not be as big a problem as you fear.
I would be more concerned about getting the timing chain sprockets lined up.
It would be wise to bolt things together and measure them before worrying too
much about
the gasket. You might even find that the new gasket improves the alignment.
When
measuring, check with the crank pushed all the way forwards and backwards (and
average
the two measurements, I guess).
