They probably won't fit your car. The application listed is for a 65-75 Cutlass. You have an 86, completely different body design.

Go with Hedman's for a cheaper header and American Racing headers for a quality, great fitting real Stainless steel header.

They are absolutely garbage and will rust up on you in a matter of no time.
You get what you pay for, don't expect much from $200 Chinese stainless steel headers, even if it's T304...

Which headers would you go with, I just want a pair that wont be any trouble installing. Thanks
Headmans, avoid the cheap chinese stuff on eBay where possible.
As they say if it's too good to be true then it probably is...

Just like the $400 aluminum Olds head on eBay, tons of machining is still required to get them straight and functional...

$400 head? I assume you mean Procomp. All reports from builders have shown very few flaws, bought directly from Procomp. The biggest issue IMHO with them is the 80+ CC chamber. It is supposed to be 77 CC which too big for us SBO guys to begin with.

This is what I am talking about:

Valve seats and guides on Procomps are hit or miss, they are not a bolt on and go head even if "finished" from a vendor...
Best to contact Bernard Mondello for a set, he does them up right.

Hedman Hedders 58160 Is this the part number for the headers I need for my 86 442 with a Olds 350. Some one on this forum said they had to modify the frame for one side to fit right. Thanks for the help
