Wanted - 331 cast iron headers 4 bolt stock or aftermarket ok

[Mike McGuire]

Hello,

I'm looking (forward) to find the wider collector cast iron headers for my 331 project motor.
The stock ones have what looks like a 2" collector.
Pretty sure the 4 bolt are more desirable, and have a wider collector (3" or so I am told).

Trying to fit with my 1955 - 300 clone project.
There was a company selling them through hot heads but they are now discontinued.
Appreciate any leads.

Thanks,
Mike

maybe trucks with 354's . i've got a 301 poly with 55 300 hemi heads . but my 354 ind came with exhaust manifolds , not sure of the exit size .

my 54 331 has stock exhaust manifolds on it . i'll sell those .

Thanks. I have a pair (or regular) 2" set, but that's why I'm trying to upgrade. Easy performance boost. Nice looking mill!

like i said the dodge truck big stuff ran the 354 chryslers in them , not sure of the exit spot but they might be the bigger exit size . matbe some one on fortrucksonly.com might know . this is my 55 301 setup with two different 6 71 setups , i like the twin stack injector the best .
