The Revolution MINI Works Big Valve (only for the W11 engine) head is among the best on the market when it comes to performance heads. This championship winning cylinder head is at the front of the pack and has been carefully engineered to perform. Comes standard with Black nitrided 1.8mm oversized intake valves and 2.3mm oversized exhaust valves. Each head is CNC'd so each and every cylinder head is exactly the same for flow. Something that can't be done by hand! Supertech makes the valvetrain with titanium retainers and beehive springs which are the lightest in the industry for high RPM engines. All of the (optional and sold separately) RMW race cams (CAM NOT INCLUDED!) have been tested on these springs so you can rest assured there are no issues with valve float or coil bind. RMW cylinder heads are used in the Grand Am winning Race Mini's along with RMW Race cams and Race headers. Inconel exhaust valves are available for extra $$.  All intake seats will be replaced with bigger seats to better handle the big valves and are finished on the industry leading Serdi Machine. Each head is vacuum checked before heading out the door. The RMW cams we also offer make a great match for this head and depending on how it is tuned can really change your MINI from mild to wild. 

This ONLY comes with Valves, springs and cam shaft caps. Everything else will need to be swapped out from the old head. The cost includes the $500 core charge that is refundable upon receipt of "Good" core. Return shipping to RMW must be paid by the customer and confirmation of cores quality by RMW staff.
