I have an 86 gn with cracked drivers side header. The car is stock, everyone seems to sell the same replacement header. Is there any brand that is better than the other. Or would it be better to replace both like the ones poston sell?

Screw a replacement header, bolt the one you have to a junk head and weld it, go slowly and add a gusset between the 3-5 cylinder primaries. Go slowly and bolt it to a head until it is cool to the touch, if you don't it'll warp like crazy.

Stock headers are the best...

Thanks for the reply, but i don't have a junk head and don't no a welder in this area that's worth a damn. And i can't afford to have the car down, while the welder thinks about weather or not he will do my project today or next month. So out of the after market headers what one do you guys think is the best?

Why don't you telephone Buick vendors about a replacement header? One of them is likely to have a properly repaired one on the shelf and would be willing to ship it to you on an exchange basis since you can't afford any downtime. A stock replacement is by far the least expensive route.
