Factory LS6 engines use the standard push rods but the valve tip height is .0236" taller to make up the base circle difference
Also the factory push rods are said to be 7.385' and not TRUE 7.4; so with that being said, I'd suggest a 7.425" length or pull the heads and wack em' .030" for more squeeze plus pop a 7.40" in and be happy
