Need headers for my Jimmy!!
 

What fits my '72 Jimmy? I'm guessing itsa 350, and has A/C, power steering, and auto. It's already dualed out, but I have a leak in the passenger exhaust manifold next to the head. I need to take care of this before I ruin either a head or a valve.

I want long tube headers that are coated, but am unable to find the right application for my Jimmy. Also, how do I tell if it's 350? Were there any other V8 engine options for 1972 Jimmy's?

Your option list sheet should list the 350 as an option if so equipped. Also the 350 will have a 4bbl carb whereas the 307 will have a 2bbl carb.

Of course, this only helps if engine is OE.

Headers for a SBC should be the same regardless of CID

I think that you need to make sure that you get headers specific to the 4x4. Any headers for a '72 chevy/gmc 4x4 should work. I have Flo-tech headers on my '69. I have heard they rust out quickly - I guess I'll find out. Headman makes headers that fit too. It might be easier to find applications for Blazers rather than Jimmys since they made more of them.
