I recently went through the same deal. When I got the car it was all original and had functioning cowl induction, the sticker on the air cleaner was 396, so thats what I am going with as replacement. I know they changed the displacement but since all the badges on the car remained 396, I believe thats what the flags sticker should reflect....Thinking about it now, I have never really seen the crossed flags with a 402 on any SS, maybe on 71/72, or non-ss BB cars.
Non the less, 396 sticker on mine.
'70 SS 396 4spd

Either would be correct, since Chevy still continued to us the "SS396" moniker for the car, and 402 cross flags indicate the true displacement of the engine. 402 would certainly be more unique, and still correct IMHO, but if you don't want a barrage of questions everytime you pop the hood at a show, go with the 396 cross flags.
1969 SS396 frame off in progress
The only place they used the 400 cross flags were on the '70 Monte Carlos and Malibus with the LS3 402. The SS396 was badged as a 396. I guess they found it easier to miss-badge all applications than to call them 402!
In '71 the badge style changed and was only used that year. They incorporated the horsepower and displacement on one decal without cross flags. They were gray & white over silver foil. They were still calling the 402 a 400, but only the Camaro SS396 was badged as a 396.
No decals '72 or later.

It wasn't a matter of being easier, it was marketing strategy. The "SS396" was such a popular moniker, they kept it even when they went to the 402. "SS402" just didn't sound right I guess. The 402 is an aftermarket item. Chevy never had that sticker that I've ever heard of.
didn't chevy label the 402 as 396 during the horsepwer wars? I think i heard they put the 396 tags on it as a shady manuever, similiar to the ls5 and ls6 something like they have the same amount of torque and the ls5 has less hp, im not sure not a history guys ut like i said thats what i heard, I actaully think i read it somewhere? There goes the memory loss again, fricken late nights…
The reason I have heard for boring the 396 cu. in. to 402 cu. in. in late 1969 was because of the new 1970 emission laws. The law allowed higher emissions output for engines over 400 cu in. The cost for Chevy to build the 402 was less then the cost to build the 396 because it did not need to meet the more strict emission laws. They still called it an SS 396 because of all the advertising and popularity of the SS 396. They did build a non SS 402 big block engine Chevelle called the 400 turbo jet engine and there was also a small block engine called the 400 turbo fire. Crazy but true.
