Promaxx heads

Being new to the forum I have no posts except in the intro page, if you don't recognize me, thats why.. Anyway I have blueprints for a serious build for my 05 6.0. I am looking at the Promaxx heads. Anyone have any thoughts on these? I am not even going to mess with my stock heads. They have 220K miles on them so they did there fair share of work.. I am looking to get extreme HP and am worried if these will take the beating.

Are those the $10000 heads people have been talking about?

Are you wanting a full competition truck or a money pit(what I'm building)?

And what hp number are you shooting for?

They are $1600 for the set. Not just remaned stock ones either.. Built thicker in the prone areas of the head. I am doing this build just to have it.. I may pull a few times at the fair and peel down the strip a few times to kill GM and dodge but other than that she will be my daily driver.. I just want that balls to the back of the seat feeling and you cant move when WOT.. Im a guy.. And for HP range I am not to sure yet.. Im blueprinting it from scratch so I am hoping to be in the 600 rwhp all set and done..

Unless you just really don't want your old heads, that doesn't sound bad for the price.

600hp is pretty easy to come by these days. The easiest way is going to be a big vgt and 190-205cc size injectors. An old saying was that 205's were the limit for what the hpop can handle. You definitely won't need heads if you checked yours and they were ok to use.

The 600HP range was a pure guestimate. I can hot rod a chevy 350 gas job and know exactly what I am going to get for HP but being new to diesels I am clueless.. I will list a part list when its compiled. I am afraid that even if my factory heads are ok, they have 220K+ miles on them and if I'm pushing major boost and heat they will fail. I am building a truly bullet proof engine for serious HP. For all I know, the set up I am planning will give me 1000 HP. I just don't know
