66gtk,
I just got confirmation from a friend who has a Roush 342 in a SPF w/ no scoop. He can use both the 289 14" style (w/ no drop) and the Roush oval that came with it, with no interference, although he said the Roush to extremely close.
I believe the 342 is a stroked 302, and your 402 a stroked 351. Not sure if your 402 sits taller, it might. Plus the manifold differences.
Go to Summit or Jegs online and search for 'K&N 14" drop base' and you'll find them. I'd buy both and return one.
