What are the best headers for the lt1? I have a 17 ss if that makes a difference. If y’all have dyno numbers for the headers only please share them

all long tubes will dyno the same. pick the ones you want.

Diameter will have an affect on performance, don't put the largest diameter tube header on a stock motor, you could lose torque and low-end. You pick the your exhaust to compliment your mods. All headers are not the same. These cars flow well, you don't even need headers if you haven't done anything to the engine.

Stay with a smaller diameter tubes unless your building a top end beast that needs to breathe.

15 RWHP. Any of them. But if you are going FBO get 2". But for a milder build go 1 7/8. Listen to one first to make sure you like the sound. Except at Atco I did not.
