Hood heat shield

Hey guys i was wondering what my options are for a heat shield on the under side of my hood. I had raise my hood about 3" when i turbo charged my car and i have the stock shield but, don't know how it i could make that one work anymore. I could cut it and piece it in but I would have to find a high heat glue to stick it to the steel. Is there a thing such as a spray on shield for hoods? I have my turbos, headers, and downpipes wrapped with exhaust wrap. Do I really need to have a heat shield?
