Best deal on TTI headers

i have them in my car, same in my buddys and in 2 recent customers cars. 2 68' cudas, 67 cuda and 70 dart. all small blocks. by far, the best fitting header in a 67-up a body, period. tucked to the body, thick flange at the head, mandrel bends. well made. they are expensive, but do you like replacing headers in 2-4 years? i don't. my buddy's were purchased in 2000 and then driven daily. rain or shine. still using em on the fresh rebuild. still great. get the c4 level. its worth the ceramicoat, and thermal barrier. if you have a hipo engine, these are an extension to it. remember, 2 sets of headers in 6 years would be the same price.
