-Skunk2 Stage 2 Cams
-Omni Power Valve Spring/Tit Retainers
-Supertech Flat Nitride Coated STD Vavles
-RC 310cc Injectors
-2 layer Headgasket (prob buddy club)
-head milled 0.020 inches
-AEM Tru-Time Adjustable Cam Gears (5 bolt) (degree cams to specs)
-stock P30 IM and TB
-Comptech Header
-ARP Head Studs

-Mfactory LSD
-Chipped p28 tuned on chrome most likely

OEM:

Looks fine to me but what will you be using for an exhaust/header?

It'll work. A better header and larger exhaust will make more power. Are you running a cat?

ok I will look into the comptech headers efficiency on the setup and also into the gains of a possible 2.5" exhaust. Thanks

2.5" exhaust and a 3" intake

Get a quality header -- comptech off the shelf is okay but if you are gonna do it...do it big..."custom"

do you have to mill the head to run flat valves? Also about how much more compression do the flat valves give ya? I am thinking about running them in a b17a1

cool so with a 2 layer head gasket and flat valves, compression should be right around 10:1 on my b17a1. Thanks

These would be worth a .5 bump from wherever it is.
