Default Injector/Fuel rail combo

I have a 2000 T/A WS6 with 350rwhp. I have done intake/exhaust and a tune. I am wanting to upgrade my fuel injectors and rails as i will be doing a mild head/cam down the road and no boost. I am shooting for a 4-450 rwhp build. My question is, if i buy the ls1 fast billet fuel rail will it fit my stock injectors, or will i need a spacer/diff oring for injectors or spacer for the mounting tabs? Also the biggest thing is when i decide to upgrade my injectors(leaning towards either a fast brand in the high 30lb range or delphi/svo 42's) will they pop right in the rail without any extra hardware or modification? I have heard lots of nightmare stories of fitment issues and fuel leaks so i want to make sure i get everything right before i spend lots of money.

Just keep the stock rails.

In case anybody finds this thread, i ended up returning the fast fuel rails as they ended up being a nightmare. The brackets had to be modified so the injectors didn't leak, and once installed most of the AN connections leaked (probably a bad install/overtightening on my end) but nothing went smooth and for the money i spent it should not have been that difficult. I know lots of people have made them work but if you have any doubts or are doing the install yourself i would just do what the above guy said and keep stock rails and powdercoat which is what i ended up doing, they dont function differently other than being a "high flow" rail which doesn't change the pressure but reduces the risk of starving injectors of fuel, and with all the problems I didnt want to risk a potential fuel leak or fire from a set of rails that i wasnt impressed with. Side note the red isn't even the same red as like the umi bars and typical "Chevy" red paint its a lot darker. I will still upgrade the injectors eventually i have decided to use the fast 36lb injectors.

Stock rails will handle twice the power you're looking to make. No reason to go through the hassle to upgrade unless you're looking to make twice that power on E85.
