So what's in the box?
Gibson ceramic coated shorty headers, GP113SC.
I've been wanting to do headers for awhile. I soaked everything in PB blaster for a couple days before I started. I was able to remove all bolts and studs without breaking anything, but... I already had two broken studs. Of course they are recessed 1/4" in the block. The driver side exhaust gasket was blown through in every cylinder. The condition of the cylinder 1 mating surface clearly shows this should have been done along time ago! You can actually see the exhaust manifold is peeled off the head (outside of cylinder 1) in the first picture below.
Since I'm retaining the EGR, and the EGR tube is priced like gold now ($400+ on eBay), I didn't have the option of cutting the tube for easy manifold removal. The top EGR tube connection was simple enough, but the EGR connection on the manifold wasn't happening with the manifold on the engine. I ended up snaking out the manifold w/ EGR tube in place, and it came out just fine after a few minutes. Damn good thing, because it took the power of Thor to remove the EGR nut on the manifold. I was hitting the wrench as hard as I could with a 3lb sledge, and it took a solid 8-10 whacks before it finally freed. Even then, it barely turned without a lot of force, so trying to get that thing off with the minimal space in the engine bay would have filled up my swear jar.
I'm waiting for some free time to finish up the install. I still need to remove the two broken studs, mount headers, cut and fit the new exhaust pipes to the original piping, and get it welded up soon after.. A new muffler is in my future, but haven't really decided what to go with. I'll likely go with the school bus muffler to keep it tame.
