Default rebuilt ls/vtec

as some of you know my first ls/vtec blew due to a bad oil pump,(had no relief valve). well i rebuilt the engine heres my set up.

b18b block bored 40 thou.
82mm type r pistons
new gsr oil pump and water pump
shot peened ls rods
ls crank
acl bearings
arp rod bolts and head studs
b16 head
buddy club spec 3+ cams w/ buddy club valvetrain
buddy club adjustable cam gears
skunk2 pro series intake manifold
stock injectors
stock throttle body
2.5" jdm itr replica header
full 2.5" obx-r exhaust
chipped PO6 ecu

i just wanted to know how this setup sounds? and if any changes should be made, i'm shooting for roughly 180whp. Also what can i safely rev this engine to? i have heard the cams stop making power around 8500-9k, can i safely take it that high. thanks for any help, muchly appreciated.

rev that bitch

how much is it revving now? 7500rpm?
peaky as hell graph, rev it out till it stops making power
you have all the right ingredients to safely rev it to 9000-9200rpm (as long as you put it together proper )

whale ***** is usless and just a bling item. get some 3 inch piping with a BPi velocity stack and K&N filter. as far as the dyno plot, i'm no expert, but i would think you would need bigger injectors and a better header. how about something to tune with/hondata, etc. hard for me to see graph clearly.

i reved it out to 8500, tuner suggested bigger injectors and a fuel pressure regulator, also he did not touch the adjustable cam gears yet.
