12 valve build help. Timing suggestions please

well I have been building a 12 valve for two years. Its come a long way.
Im looking for advice on any other things that you guys would recommend.
I'm trying to keep the truck on the edge of streetable but I want to have more fun spanking dmax's and powerjokes at the truck and dyno days.
not sure what hp and tq il be at.. But im hoping for 700plus.. what do you guys think ill be at?

CDS is doing my bump right now and they said they were going to do 24 degrees of timing. a few guys on cumminsforum said if i was giong to be turning higher rpms maybe go to 28 or so. what do you guys think. They told me to check at this forum. More knowledge on the mid to higher performance stuff.

This is my parts list..
Air dog 2 200
Laser cut delivery valves
SDX 5x.018 with stage one bodies (They said they remove the filter for more flow?)
My pump is being benched right now by Columbus Diesel supply
they said they should get about 500 to 550cc out of it.
timing is going to be set at 24 degrees (is that a good timing)
KDP
5kgsk from cds
afc is gutted right now CDS is looking for internals for me so i can tune the afc
water meth injection
haisley pushrods
retainers and keepers
head studs
fire ringed
head resurfaced
cylinder heads resurfaced
tork tek ofv 060 and have a 070 on hand (not sure which is better)
mack/rack plug
built transmission automatic
source auto twins
bd 64/71/14 over s480 1.32 ar forget the rest of the specs on it.
60lb valve springs

im probably missing a few things..

It's annoying when you post the same thread in two different sections.

Help with 12valve build.. TIMING suggestions as well - Competition Diesel.Com - Bringing The BEST Together

Different crowds in different sections, means more feedback. Not everyone goes through every section to help people out. You both wasted time of your day to be negative and not helpful, why bother? My same thread is on other forums as well, getting more feedback to make good choices. Common sense, and you would be dumb not to use your resources. Sorry it bothered you both. Just ignore it??

I think *24 is a little high. But it depends on how everything is tuned on your truck. *24 is great for the summer but you will hate it this winter. Are you doing alot of street driving with this or what. What are your plans for the future.

If your running over 4k rpms 60 lb valve springs are a tad weak. Ditch the laser cuts and get a set of comp dv's. Unless you plan on spraying. As far as timing goes we need more info from you. Piston design, injector spray angle, cam specs, injection pump specs. Also remember that water/ meth increases timing as well.
