Default Stock LS1 Rockers w/LS2 Stroker

I have heard that if you use LS1/LS6 stock rockers with an LS2 block you need to put shims under the pivot plate for correct valvetrain geometry. Has anyone heard this? The link below is where I got this info:

My dyno numbers were a little lower than expected. This is the only thing I could think of that might have caused a problem.

485 RWHP 439RWTQ

W2W Built LS2 402 Shortblock 12cc Valve Reliefs
Texas Speed Race Ported Patroit LS6 Style Heads 59cc Chambers
Comp 7.4 Pushrods
Texas Gaint Cam 248/254 6**/6**
Stock Rockers
Fast 90MM Intake
Nick Williams 90mm Throttlebody
Halltech Stinger
Comp Lifters OEM Replacements
42LB Injectors
Bosch 420L Fuel Pump w/Speed Inc. Rails
Kooks 1 7/8 Headers w/offroad X-Pipe

I figured the motor would make 500RWHP and about 480RWTQ!

Any suggestions?

I'd like to know this, too... You ever get it figured out? I'm looking at doing a similar setup, also with the stock rockers.
