BBC HEADERS for 4x4

[90 GMC 4x4 454]

I did a BBC swap in my 1990 GMC 4x4. The motor is a 93 454. Where can I find headers for this?

these are not for gmt400s but they might work if you have a tight budget https://www.ebay.com/itm/2254124610...HLwH3+OFgUj5Pza/141DOQTA==|tkp:Bk9SR5qdwtO5Yg there are way better options out there but you will pay a lot for them

Those won't work. The collectors hit the frame. You need GMT400 specific headers.

I bought a set like those but drivers side was about 2" above the front drive shaft. No way to hook up collectors
