Rotating engine clockwise

Hi, I am in the process of doing my valve clearances and stupidly rotated the engine about 90 degrees clockwise instead of counter clockwise, would this hurt the engine, I checked and all the timing marks line up fine.

Each cylinder's T mark is on the flywheel.
Do the process all over and check the cams' alignment marks to make sure.

You don't wanna slap any valve with your pistons now, do you?

Thanks for the very rapid response! yeah I checked front and rear cam alignment marks with the flywheel T marks. I take it if they are still ok no harm done?

You didn't forget the 450 deg turn counterclockwise to set the rear cylinder's T mark. Did you?

Sorry makis, just to clarify I haven't removed any cams yet I just turned flywheel the wrong way during checking valve clearances and wanted to make sure this wouldn't do any harm? sorry should have made that clear at the start

Since you haven't removed the cams, you can rotate the crank which ever way you want. No problems there.
However, measuring the valve clearances, needs the crankshaft and the cams to be at a specific position in order to get the correct reading of the clearance measurement.

Rotating the crank counterclockwise, setting the cams on their marks parallel to the head's surface and facing outwards, so that the F T and R T marks align with the crankcase cover's mark is the exact position to get a correct valve clearance measurement. That is the "compression phase" of the cylinder and not the "overlap phase" on which the marks on the cams are facing inwards.

Read the manual closely
