What is your question?
There was a clicking sound and we were told it was from the spark plugs being loose. If they can’t fix it they said we would need new heads.
How long has your 2012 Chevrolet Silverado 2500 HD had this problem?
It got bad the last couple of days but was minor for awhile before than.
Furthermore this question needs to be addressed to whomever is going to do the actual work - any other estimates are irrelevant.
