455 G-body headers | GBodyForum - 1978-1988 GM A/G-Body …
2009年7月20日 · I had an 84 cutlass with 461 in it with ceramic coated headers that fit within the frame. I got the car with the headers so I am sorry I don't know what headers they were. I have seen on some of the Old's forums talk of headers for different model cars that will work with minimal massaging of the firewall or a couple dings in a tube.

2009年2月5日 · The 455 sits up higher because of the physical size of the block (it is called a big block) so the heads are up higher compared to the small block that sits lower so the headers interfere with the steering shaft.

2010年1月6日 · Other than this, mine went in like they were designed by Oldsmobile. I don't know if a 3" drop base will work with a QuadraJet. I have a 2 1/2" filter on mine with a slight drop base and it works fine with my Edelbrock carb, Performer intake and factory hood insulation.

2018年1月31日 · Hello everyone, I've recently been considering putting headers back on my car and the general consensus seems to be that American Racing Headers are the way to go.

2009年7月1日 · 455 I believe hooker makes the only swap header for this set up and there over 450 a set and both rear tubes go around the frame, the safest cheapest bet would be to use the W/Z manifolds which are a little cheaper but still expensive.
