1 5/8 headers

not sidetracking at all my friend. My thought is plenty of guys are running trick flows with existing headers that have been around forever with these flanges. Can’t say as I have heard of anyone with any issues??
Maybe I’m making it confusing, I’m not implying any issue but more a curiosity thing. I’m pretty sure the TF ex port is uniquely shaped vs all the other LA based heads and wondering whether a header flange similar in shape and how the pipe is welded is anything to consider. Probably not, just lots of free time to let the mind wander today:eek:
