all headers fit, you just have to take your time. TTi's are stupid expensive. I like Hooker Super-comps they are 2 piece, easy installation. But I have also used Summit cheapo's w/ no issues at all. These are cheap summits w/ PS
Just be sure they have a thick enough flange on the cheapo headers. I hated the ones back in the 70's that warped and leaked with the very thin flanges. I know my TTI's have the nice thick flange that looks like a 1/4" thick. I can say they have been on my car since 2011 and still have the same header gaskets on them as they have never leaked. The Hedman headers I ran on my old 440 worked ok but the flange was not as thick as the TTI headers flange. Ron
