My 73 Bonneville has points type ignition. The later years had electronic ignition distributors, which had .045 or more gap. If you're engine is points type, the gap is .035.

First, you try Nambe Metal Polish. It can be purchased at many different outlets like Neiman Marcus, Dillards, Bed, Bath & Beyond. $10 bucks or so. Use with 0000 Steel Wool. But if you want your piece to be like new, you send it directly to Nambe Pueblo. I had a piece that looked beyond repair, and it came back as if it were new. For the life of me, I can't find a website for them. But you can call Nambe Pueblo (505) 455-0142 Just go to Nambe.com or call 1-800-443-0339. Repolishing costs 15-20% of the current retail price of the item.
the gap on the distributor points is .016, the timing is advanced 4 degrees and the spark plug gap is .030
That depends on what type of distributor/ignition you are running. Point style, good rule of thumb is .035. HEI is usually .045.
How do you set distubitor timing on pontiac 455?
Depends on what type of ignition system you have. If you have a vehicle made before 1975 with points, about .030- .035 is an acceptable gap. If you have an electronic "hei" ignition you can run larger gaps .045-.060 is common. On a street driven car there is little to be gained in power or mileage by fooling with plug gaps, unless the vehicle has ultra high compression, is turbo or supercharged, is running extremely lean, or has a weak ignition. Most spark plugs will be gapped correctly right out of the box.
No, they are completely different.

.030-.045 lower side for points and higher side for HEI
