Is the improvements to the new LA heads, enough to not reproduce the W-2 head anymore

Ported aluminum Eddy's, sold 'em to a member here.. They " flowed 280 ,with the stock valve job" I considered fair. ( Thank you,fellow FABO member..) I always loved the immediate response the W-2 's worked with deep gears (& converters) hammered with.. When I built my 408,( mentally) Spec's W-2's..couldn't find iron,couldn't find a set,come high dry or water.. Now everyone's doing improved Magnums,( love them..),cheap eddies, )... Why not W -2 cast irons? Such a wonderful cylinder head, ( Hate INDY, won't deal with them, Brodix too pricey..) Chime in,good or bad..
