I just tried putting Firebird headers in my T-Type with a 455 SD and the passenger side hits the lower control arm bracket and the driver side hits the firewall a little. I bought the Flowtechs so maybe that's the problem. Thinking of cutting the tubes and move them a little. Wont take much to maje them fit. Anyone else gotten further than this?
That's funny, those are the headers I have and was wondering the same thing. I am going with a set of Mad Dog Headers probably, these headers are bad enough to do once.
