Fuel rail custom
#4
You want to anodize the inside of the rail?
I'll second the fact that the stock rail is perfectly adequate and even the several production aftermarket rails are overkill for 460's. There are many hi-powered B6 engines on the factory rail. Your time and effort is better spent elsewhere if looking for performance.
If just looking for "looks", I can think of a few other places to start under the hood for my time and money.
You can research the wall thickness of the various production aftermarket rails to get a good idea of the stock to use is you insist. If not using an RRFRP and sticking with a the Walbro 190lph, it's tough to imagine reaching more than 90psi in the rail. Use that as a baseline.

If you are looking for that last %age of security, you can drill and tap the aft end of the stock rail to make it dual-feed. You have access to a shop, drill out the rail and tap it for a 3/8" or whatever barb, and feed both sides of the rail. That will get you uniform pressure at both ends. You certainly don't need more fuel, but even pressure is ideal.
In the past, there was a big "issue" with cylinder#4 being prone to damage while other cylinders were fine. It was thought on boosted cars that the aft cylinder was being starved for fuel under hi flow. Later is was discovered that most of those cars were victims of the factory coolant routing and overheating due to bad coolant flow and not fuel starvation.
