Is it worth changing a head gasket on a lt1 after its blown?
Depends on how miles and year vehicle you have. Can you post back with more details?
It usually works good after it is repaired if done correctly, make sure they have the heads checked and resurfaced or replaced if they fail testing and the cooling system is checked and is flows properly. It won't be cheap but it's cheaper than buying a whole new engine unless that is what you want to do.
