The Medium Port, High Velocity Torque Monster!
In keeping up with the GM's trend of larger bore sizes and increased displacement, AFR is proud to release the 215cc LS1/LS2/LS6 version of our popular Gen III product line which is aimed specifically to maximize 4” bore combinations (364 - 408 CID). However this head is very versatile and could also be considered for aggressive 346 applications and should also be a prime consideration in larger stroker motors as well (415 - 430 CID) if the focus of the build is more aimed at enhancing street performance than all out strip performance (where our 230 or 245 cc offerings potentially make more sense). This is a very effective design offering serious velocity while still being able to provide a significant volume of airflow, enough to generate well over 600 HP at the crank. This head will also work well on any forced induction or nitrous applications from 346 - 408 CID; larger engines should look to our 230 offering. It of course comes equipped with AFR's trademark 3/4” thick deck and thicker port and combustion chamber surfaces as well. If you're looking to see that blue oval in your rear view mirror instead of your windshield, look no further than the AFR 215.

Note: Hydraulic roller cams in "LS" Gen III engines typically experience valve float at 6600-6800 RPM's. If you are using aftermarket rocker arms valve float will become prominent and AFR highly recommends upgrading to the AFR part #8019 spring. If you plan on running over .600 gross valve lift and/or 6600 RPM, AFR suggests you upgrade your springs to AFR part #8019. The upgraded springs have higher seat and open pressures (155/410+) to better reduce the risk of valve float in more aggressive applications.
Note: The AFR 215 requires a minimum head gasket bore of 4.135 regardless of bore size and is a direct bolt on requiring no special parts.
Note: LSX bead locks and aftermarket bead locks are not interchangeable. GM made their bead lock radius and depth different. AFR locks are the same as GM LSX.
