So those headers with a TF240 head on a 400 block according to TTI they won't fit. But the 2" stepped to 2 1/8 inch will fit. I'm calling TTI to get the final lowdown on this. I will surely report back what I found because I'm so sure there are people like me out there putting 451, 471 and 512 in street A bodies that need a good header solution. Yes I would like to find a more cost effective solution but I need at least a 1 7/8 and Hedman doesn't offer that and don't want the Schumacher. I do have a set of 5903 hookers super comp that are on my 79 Magnum, I wonder if those would fit???? Anyone try those??
