I've used the tti in an a body with both RB and B engine. They just fit. Be careful when ordering. If you have after market heads, can cause a fitment issue. I was running factory heads. They have a couple of choice depending on setup.
I`ve got TTI 2" headers on my 68 barracuda, 440 w/ raised port heads, fit like a glove,. -tite glove tho ! have an aftermarket front end, don`t think this set would work w/ a stock front end on my car.
