1954 chevy 3100 235. Tired of the exhaust leaks I pulled off the intake and exhaust manifolds. Though it might be nice to not fill the cab with poison gas every time i take her for a spin

Found a pretty good exhaust man. at a local boneyard, at least its way better the the pitted one i had. Been looking around online and from time to time i see pics of 235's where they've replaced the two outer mounting studs with actual bolts to better pull the exhaust manifold in to the head. Thoughts and experiences?
