They feature stainless BrianCrower(BC) valves with the BC race spring and titanium retainer package.These cylinder heads receive the same high quality port work as the stage 2 heads along with additional work to the combustion chambers.We do a five angle grind on the seats which is done on a Serdi head machine to accommodate the BC valves.  These heads are capable of 8000 rpms without the risk of valve float and have the potential of 1000+ WHP with the appropriate, turbos, engine, etc.</span><br><meta charset="utf-8"></p> <p> </p> <p><span style="text-decoration: underline;">More Info</span></p> <p><span data-mce-fragment="1"><meta charset="utf-8">The cylinders heads are responsible for getting air into your cylinders.  To make big power you needs lots of airflow without compromising velocity.  Our cylinder heads will outflow the stock heads by as much as 40% while maintaining enough velocity at both high and low rpms to provide substantial torque and power increases. Our cylinder heads are expertly ported and machined to perfection.  There are places out their that get a bit aggressive when it comes to porting which can lead to loss of power or worse case scenario, destruction of your heads!</span></p> <p> </p> <p> </p>
