I'm pretty sure that GM no longer sells bare LT4 heads.

GM part # 12363287 casting # 12555690 : they are still in the GM perf parts catalog 2002 but they are not bare.

It is actually cheaper to buy them assembled anyway. I looked into it last year and had Jeff Kopp look up the pricing for both. Bare was a few hundred $$ more.
