Ill throw out my 2 cents. As stated above there is a chance there could have been some damage. If you decide to re ring the truck youd need to pull the pistons out anyway. It would give you a chance to check everything on the bottom end with a fine tooth comb. If it were me Id throw the 4.8 pistons in anyway for a CR bump that way. And the tr220 cam is a great performer for a DD truck if that is what you are going for.
Completely off subject but If you were willing to get work done for the heads finding a set of 243s to mill and throw on there with the 4.8 pistons would be a very interesting combo for what you would have wrapped up in it
