At least most are. There was a long thread a while back about 243 heads and some other numnber. Net: Just a casting number.

Best heads to replace LS2 (243 casting) seem to be the L92/LS3 heads. or one of the aftermarket like AFR 205 or 225.

Theres a rumor going around is that fast is gonna make an intake for these L92 heads .the only other option for this head /intake combo is the L76 ,this intake does not flow well enough for big cube forced induction motors ,i am looking for another head besides the L92 ,the 225 afr would be a good choice for deeper pockets than i wanna spend

I would recommend in dealing with a reputable company rather then take someones word, remember he wants to get rid of those heads. I would stay with AFR heads and depending on your needs there are two being offered 205 and 225.
