Got my heads on...now it's Dyno time.

Well, I got my heads on a couple days ago, and I'm waiting to get on the dyno. But in the mean time I'm going to install some 1.6 rockers and get a tune. For now I'm going to get just a mail in tune. Then later on this summer a dyno tune. Anyways, just kind of curious to see what you guys think I'll make on the dyno. Here's a picture of what my heads flowed.
Here's a list of my mods:
Alum. Drive Shaft
3.73 Gears
SLP Clutch Kit
160 Powerstat
Desreened MAF
Flow Master American Thunder w/ Cutout
TPiS Mid-Length Headers w/Y-pipe-Jet-Hot Coated
MAC Off-Road Pipe
Taylor 8mm Wires w/MFU OVC Looms
!AIR & !EGR
G2 CAI w/ K&N Filter and Modded Filter Case
Racetronix GSS340 Intank Fuel Pump
TB ByPass
LT4 KM
1LE Intake Elbow
Air Foil
TPIS ZZ409 Cam-226/226; .520/.520; 112 LSA
New Hydraulic Lifters
TPIS 700-132 Valve Springs
New Timing Chain Gear
Valve Seals
TPIS Head Gasket-Impala Head gasket.

Oh, it's a 96 Z with a T56. So, what do you think???

My guess would be 375 RWHP.

Given that you're doing the tune (and can directly affect the outcome) I'm going to second that vote!!

Actually, that was an "ideal situation" guess, so it wasn't just a biased opinion.

325-330 RWHP would be right for stock heads.

Yeah I made 325rwhp with stock heads and a Hotcam kit so it should be make more than 350rwhp for sure. Good luck.

Depends on type of dyno too. Let's guess 1/4 mile times instead!
