From mild to wild and everything in between, WSRD offers cylinder head and engine packages to suite your application and power needs! 

**All cylinder head package pricing includes a client supplied cylinder head core. Please ship WSRD your completely assembled cylinder head. All unused parts will be returned to you. Once the cylinder head is received WSRD will tear down and inspect your supplied core. If the cylinder head core does not pass inspection and can not be machined, WSRD will reach out to you ASAP!

Please ship your cylinder head core to the following address: 
Whalen's Speed R&D

After you complete your order, please print off and include your email order confirmation and include this in the package with your head core.
