Replacing main bolt in 5.7 should I worry

In case anyone was wondering. I loosened both bolts and the cap didn't move at all, that being said I didn't try to move it either. I removed one of the bolts and replaced, hand tight. Removed the other and replaced, hand tight. Then torqued each to the recommended 20 lbs, then added the recommended 90 degree turn. The cap never appeared to move throughout the whole procedure.
