I looked at the factory manual last night and it does not mention replacing the bolts. Fel-pro is the only place I've seen TTY mentioned. I'll just get the regular bolts. Thanks for the input.
Factory uses 2 1/4" 5/16 NF, with full threads. Its tough to find 2 1/4" so we use 2". Grade 5 is fine. $2.75 at home creepshow. If you get fancy and get stainless or chrome, use anti seize but other than that, its just a bolt.
