Like fastball mentioned there will be wiring issues. The heads may not even bolt right onto the block. However there is a member on the Legend board that did take the block from a 3.5L RL and used his Legend heads. (disp = torque and the Legend heads are performaced tuned) Prior to this build he ran 12 secs. w/ nitrous. I don't think torque steer will be nasty because of the longitudinal placement of the engine. This is not a traditional FF. If you plan on doing a Frankenstein on a Legend motor look into taking the RL block and Type II heads. The Legend is not a DOHC, it is a true SOHC because on a V6 there are two heads...each head has only one cam.
Actually the newer legend have c32a because they are 3.2L. I did some reasearch on the two motors and found that the spark plugs plug inbetween the cams on head and on the legend they plug rite into the block next to the head.
