Hi Paul,

I missed the beginning of this thread; can you tell me what the intended benefit is of the steel side plates? Are these a replacement for an aluminum factory piece? (I haven't torn one down yet)Would these be recommended for a typically rebuilt NA 13B, using Terry's induction and ignition systems? I hope to be getting about 165+/- HP. Thanks.

The highly experimental steel side plates in conjunction with aluminum water 
jackets will reduce the weight of the engine by about 50 pounds. No need for costly 
coatings on cast aluminum end housings. Easy to overhaul.
