If you already have the dual exhaust manifolds, see if they are marked W and Z. You might already have the correct ones.

Obviously i stuffed a 455 in my car.. the biggest hurdle your going to run into period is your exhaust.. i used stock smog manifolds and the passenger side worked out perfectly.. the driver side on the other hand.. well ya.. lets just say the manifold dumps right into the frame where the lower control arm bolts to it..
