Well I've finally finished removing my intake/exhaust manifolds to replace my leaky old gasket.
Now I'm kind of nervous about progressing any farther. I am looking at the bolts that came out of my exhaust maifold and the ones I ordered to replace them are studs.
So what gives? I have P79 heads (car is an 82' N/A) and all I could find was studs, so I went ahead and ordered them. You could imagine my suprise then when I removed not studs but bolts from the exhaust manifold. Am I missing something here? Do I just install these studs in place of the bolts? Or did I goof up my order somehow?
Also the bolts at both ends of the exhaust mani. were sheared off beneath the surface. What is the best way to remove these? My default solution is to drill them out as carefully as I can with a left-handed drill bit, but I was hoping someone might have a better way (or maybe just some solid advice on actually doing that)?
Lastly any advice on the best way to clean up the mating surfaces? I was thinking a can of brake cleaner along with some razor blades for scraping will do the trick, any objections?
