340 headers?

Thanks for the info, abodyjoe, you helped me make up my mind on whether or not I would instal the factory cast HP manifolds or TTI's. I for sure, cannot, even though a lot of people like them, pay around $800.00 for the TTI's (that includes currency exchange and shipping to my door), for something that still will discolor, and rust. I thought they were so good that they would last forever. Sure, they may perform better and fit in better than any other header, but to have to oil them down while in active or ceramic coat them and then watch them rust is just not my idea of a good deal. I will take the 15 less HP in trade for durability, quiet and ground clearance with the HP exhausts. Thanks for the input!!
