I do believe the heads will bolt to the block because I have used nsx head gaskets on my C32 because they were MLS and did not have to modify them a while back... but I really doubt that the intake manifold would bolt in between them afterwards... not to mention a set of nsx heads would cost probably more than he paid for the car.... just tell him to get a set of headers, a full dual exhaust catback, an intake and spray a 70-100 shot on it and he will be very surprised at how hard it pulls...
