Exhaust manifold

[jeff l]

6 months ago I finished a new rebuild and I put headers on, my problem is the collecters touch my front driveshaft and loosen the header. I want to go back to manifolds but am sure what years will fit a 1986 Jimmy. My 350 block is a 79 I think, w/ the dipstick on the drivers side. Thanks for any help.

Doesn't matter what side the dipstick is on , stock manifolds should clear . The dipstick should come out the outside of the manifold .

I can check my 70's manifolds lying loose on my newer block sitting on the floor when I get home tongiht .

Just bend your headers. Come along, 2x4 wedged in the right spot, etc.

The 305 manifolds that came out, that I threw away wouldnt clear something I think it was the dip stick

Have you done that? Do I take them off? Is it ok on ceramic? Thanks

I did it on my Hedman Elites. They are coated, not sure if they call it ceramic or not.

Wood or cloth is not going to hurt the finish, maybe the bending, but it didn't mine. You can also do it hot if you use wood, to put less stress on everything.

Thanks I will try that, it seems like the cheapest fix.
