They are also a good investment if you plan to go turbo, as they allow you to adjust the amount of air and the timing of the transfer of intake and exhaust gases while under boost (particularly good in na-t applications).
Just do yourself a favor and don't get cheap crappy ones that the allen bolts can slip on. This could result in CATASTROPHIC valve overlap and valvetrain failure. A tip: once you are done with dyno tuning and have your desired intake/exh timing, locktite the allen bolts and torque them down so they will NEVER slip. Good luck!

this is plainly and simply incorrect. The purpose of cam gears is to be able to adjust (on a dyno for the most part), the timing of your valves to attain your desired powerband. Typically, people advance the intake and retard the exhaust cams. The result of this is more air in the cylinder from the advanced intake cams, and a more complete combustion due to the delayed exhaust cam. In NA applications, yes, the effect is significantly more understated. However, dyno tests WILL prove (with proper adjustment) that more torque and horses are extracted at an earlier point in the powerband, and it levels out to create a smooth torque curve, as opposed to the factory's dramatic vertical upswing beginning at about 3500 rpm. The reason my esteemed associate thinks that it will do "nothing" is that the engine is tuned quite effectively for its stock form and tune. With the addition of aftermarket parts, like exhaust, tuners, intakes, even cams, the micro-adjustment of cam gears can actually have a profound effect, to the "tune" of about 15-25 horses and similar torque numbers, and a more desirable powerband.
They are also a good investment if you plan to go turbo, as they allow you to adjust the amount of air and the timing of the transfer of intake and exhaust gases while under boost (particularly good in na-t applications).

thank you, im running an automatic na, with intake, headers and exhaust, i am looking into dyno tunning just many places around my area (Lynwood CA) mainly do Muscle cars, but im trying to squeeze a little here and a little there to get more power, i will invest in the hks's for better looks and as you stated with some of my mods illl prob. get some power as well
