Well that SHOULD have been common knowledge. Who spins 600+ WHP pulls w/ stock retainers and valves?? Even if you were gonna pull to head to freshen then up w/ OEM parts, common sense would kick in and most tuners would opt for some Supertechs (which in my opinion are at the top of the game right now) or something other than OEM, and some aftermarket springs/retainers. And yeah you don't need aftermarket cam gears to get 800 wheel, but shit he's running stock b16 cams. Most he'd get by dialing in the factory cams is 5HP, and the magic formula for that is (roughly) -2i, -2e (plus +4 deg timing). But the timing equation goes out of the window due to elevated boost levels.
