Not sure on these cars. On GM trucks for instance, like my 95, the bolts break off easily. In my case, I have a bolt head snapped off a back bolt so I now have a nice ticking gasket leak.
I don't want to go through that on my Lincoln, but because everyone says Mustang shorties are a nice gain on a stock lopo and they seal nicely, I'd like to give it a shot.
Everyone here who's done it, what have you done that was successful? Did you just soak the bolts in PB Blaster, heat them with a torch?
Also what's the best way to get the new headers to seal? I know that stock manifold gaskets are the best to use (for aftermarket headers, not manifolds), but that permatex copper silicone gasket maker is better, gives it a factory-like seal. Is it a good idea to have a machine shop machine the surfaces flat so they'll mate to the heads better? I thought I remember reading that stock shorties don't warp like aftermarket shorties do, but I assume it may be a good idea to get them checked.
