A TSP Torquer 2 or 3 would do very nicely as would TSP's 233/239 or its MS3 or MS4. All would be pretty mild in a 402. Most people put 240ish/250ish duration cams in 402's.
I would let that determine what cam to run, but I think a good mild cam would be a 224/230 on cathedral port heads, or a 224/234 if it has the rectangle ports. LSA on either around 112+2
