Double nut the studs and nip them up so they're seated, but don't torque them hard.

Is the piston still on the connecting rod or loose? If it's on the con rod install the metal cylinder base gasket, get the cylinder on the studs and squeeze the piston rings around the locater pins as you lower the cylinder down on the studs. Once that's fit down, spin the flywheel by hand to make sure the rings are good and everything turns. Then install the head and torque in the crisscross formation.

If the piston is loose, install the piston pin retaining circlip that faces into the frame and then install the piston into the cylinder on your work bench. Take the whole piece to the studs and lower the cylinder/piston down to the connecting rod. Install the little end bearing and push the gudgeon pin through the piston and install the last circlip piston retaining circlip. Then push the whole thing down until seated and repeat flywheel/head steps.
