LT1 exhaust manifolds

I have the notorius broken bolt syndrome, left bank, last bolt on the header, with a nasty exhaust leak to boot. I've been told these manifolds are junk, does any one know what after market headers will bolt up to the engine pipes without any hassle. I'm not lookin to race, just upgrade.....96 LT1 cop car...thanx in advance

hooker makes good headers that will bolt up, just call them and tell em what kind of car you have and they will tell you wich will fit. then just order online.
