Default shouldnt i have iron heads on my 6.0L?

i thought most truck heads were iron? i have a '01 HD with the 6.0L, just happened to notice it has aluminum heads... ive always complained about this truck being sluggish and having no power... just making sure someone didnt swap in a junk motor before i bought it.

also, just to make sure, where are the block #'s located and whats a good site i can lookup the numbers so i can make sure its a 6.0L?

Neg, HD trucks have the same 6.0's the other trucks have, 2500-2500hd, denali.. The early 6.0's are the only ones with the iron heads.. Late 00 they started to put aluminum heads on the 6.0 engines( ALL OF THEM lq4 and lq9..

my 01 was sluggish at first. but after I installed the long tubes, duel exhaust, and intake it pulls much better.

well i have a vortech v-2 sitting in the garage... soon as i get the money for the missing oil lines, a blow off valve (5-speed) and some piping and an intercooler it will go on. that will take care of the sluggish-ness
