What is the best fitting headers for a 70 cutlass with a 350?

 

Hookers

 

I thought ARH was making headers for small blocks now? They are nice but pricey...............stainless

 

Yes, they are.....and yes, they are !

Although, I the G-body versions on their website, but not an A-body version....

 

The a-body headers are being sold exclusively through Smitty at M&J Performance. I have a set - very pretty - but haven't installed yet. Supposed to be a "drop in". Hit up realoldspower.com, as a few folks have started doing installs and are posting some pics.

 

Good Headers cost $$$. Thick flanges will help prevent sealing issues. I saw a set recently that were a FAT 3/8" thick and maybe closer to a 1/2". All of the cheap ones are 1/4" or less including some made by Hooker.

Our Olds do not enjoy a proper bolt arrangement to seal the exhaust manifold area (especially with a Header). You need strength in the flange to help prevent movement during tightening and warpage from heat.

Hookers are nice but ironically they are all built on jigs, why some fit some dont is beyond me but it happens

 

doug thorleys hands down with a mini starter

 

For $ 850 they better fit right

 

I went with Hookers and am happy with them.

 

Im running a really old pair of blackjack headers i think they where from the 70's ., they have really thick flanges and long collectors. I got them in a parts deal. I blasted them and painted then with vht paint. I dont know what the new blackjack headers look like but i haven't heard of alot of guys running em either.
