Doug/TTI Headers with Stock K to After K

Hi y'all,

Has anyone used Doug/TTI headers in a stock K frame setup and had any issues with them fitting in the car when swapping to a HDK or QA1 etc?

With all the companies making suspension-specific headers, I really don't want to have to buy new headers. I am looking to get a set of headers that will work with an aftermarket K (PS rack and DD shaftt) and also a stock K that has say biscuit mounts and a stock manual box.

Please let me know what you guys know!
