Ported LS manifold on a b16 head OBD0?

Hi, Ive search like a madman, and still wondering if an '91 LS manifold will fit on a OBD0 b16. Ive found one thats ported with a matched throttle body. The LS runners are shorter than the b16’s are they not. Not sure if it’d be of any benefit other than the increased flow. any thoughts? is it possible?

Never mind, I answered my own question. No she wont:argh:
