I think this would be worth looking into! Since many of the factory LS heads are aluminum, they would be easier to saw and cut apart for the do-it-yourselfer, and welding them together would also be easier than a cast iron head. I've even seen the LS heads on ebay sell pretty inexpensively, sometimes as cheap as $100 a set complete. So I think its well worth looking at as a possible up and coming new alternative.
