i just checked out a set of b heads today......it looks as though the ldc will work it might need a little tweaking but it looks very do-able
also d'agostino racing has taken over production of the ldc cooling mod
no drilling u just use the exisating freeze plugs at the back of the head........as for the b heads im not a 100% sure but i think they should be the same
it cost me $500 2 years ago for just the blower and i picked up 50 rwhp and that was with a stage 3 port job..........now i hear theyre comin out with a stage 5
