Stock 340 Manifolds or TTI Shorties?

The old "Appliance" headers worked well for me and lasted 40 years, until last year when I took the 340 out for storage. Used "Blackjack" headers on my Chevy's and they were junk. The Appliance headers were a thicker gauge then most others. Another company bought them out, I believe in the upper 70's and they were never the same. 2.5 collectors, attached to 2.5 pipe w/ turbo Walker mufflers. A great setup for what I had.
