Upgrades to my stock 273 67 Dart GT

Back again looking for some insight! The TTI Headers per their site recommend buying certain mini starters. I searched around on the forums and noticed a lot of people talking about mini starters from dakotas etc. Just wanted to see if theres any specific starters preferably something cheaper/easier to buy say from summit etc. That you guys would recommend or vouge for to fit with a 273/tti setup. Thanks all.
