Hey guys, bear with me, I'm a complete noob with it comes to doing anything in a car. I've got a D15 head from a 91 CRX DX with the exhaust manifold stuck to it. I got the shield/cover off, but I can't get the nuts for the actual manifold off with my socket wrench (small one). Nuts looks like they're the self locking kind, and my socket keeps slipping off or I just can't exert enough torque on the nuts to get them off. How do I get these dang nuts off? Do I just use a bigger wrench? Why am I doing this? Oh, for fun. The head is actually pretty shot, it's warped and corroded up like crazy around the oil/coolant channels (I think that's what they are). I kinda wanted to clean it up and have it as a coffee table ornamet or something (the valve cams and rockers are all in decent condition and look kinda cool). The pistons make awesome coasters too!
