School Me on the Injectors
I'm old school SBC with carbs. Just starting to get into LS engines. I have a 2001 LS6 engine I'm putting in a restomod .I want to remove the intake and clean it up and remove the injectors. Is there anything I need to know before I remove the injectors? Whats the best way to clean the intake? It seems just to be just very dusty from the build anda little road grime? Should I put a little lube onto the injectors O-Ring when I reinstall them? Any help would be appreciated.

I don't think there's anything to be concerned about taking them apart. Yes they are easier to reinstall with Lube. Or should I say they are very difficult to reinstall without. If you try to put them back in dry you likely will mess up some O-rings before you're done. A new set of O-rings will probably come with a tiny bit of Grease and the o rings cost about nothing so there's no reason to not use new ones.
I think you'll find after a steep learning curve, tuning on an LS engine is a whole lot easier than it used to be with carburetors. Yeah, guys got the carbureted cars to run but probably .1% of those cars ever actually ran at the proper fuel mixture.

I would make sure the O rings are compatible with a petroleum based lub before using anything other then a silicone lub. If you use a petroleum based one it will swell the O rings and deteriorate them if they aren't compatible. I always use a silicone based one just to CYA.

I would use a synthetic lube on the injector o rings
as far as making sure the injetctors are not clogged I do not think simply cleaning them with brakeclean will work---As they need to be purged under pressure to clean them out
Many companies offer injector cleaning very cheap---It all depends on how long they have been sitting un used
ALSO to determine if your injectors are larger enough for your combination industry standards reccomends that the WOT duty cycles not exceed 80% The only way to know if you have outgrown your injectors is to have a tuner log your duty cycles---If they exceed 80% at WOT in 3rd gear (auto trans)you need larrger ones to accomadate the added HP---otherwise you will lose HP and risk running lean
