Default 12 mm bolts in center of cylinder head 1.8 l engine

I am attempting to remove the cylinder head on my 1.8L engine Nissan Sentra. In the center of the cylinder head are two 12 mm bolts which are not discussed in the Nissan engine manual. Any idea if these need to be removed along with the 10mm head bolts around the head and the proper order of removing these two 12 mm bolts to avoid warping?

Thank you for a reply.
