Suggestions for mods for 1993 non-supercharged Bonneville SE
Don't use a 160 unless you have a PCM chip tuned for it because you will just lose gas mileage. Go 180. Ported exhaust manifolds will be much more cost effective and net you nearly as much gain as custom headers. Weld the outside of the flange while you have them bolted to something very rigid, then grind off the internal flange welds. Then use a high temp ceramic paint on them.
