2" stepped to 2 1/4" headers ????????? I'm looking at maybe picking up a pair of 2" stepped to 2 1/4" headers with 4" collectors. The motor is a built stock cube LS1, high compression, AFR heads, Victor Jr EFI with DP and a Wilson 4150 throttle body. The car is getting built to take the stock cube LS1 nitrous record. 
Are these headers too big for a 346? The car has 1 3/4" stepped to 1 7/8" Edelbrocks on it right now.
