The engine is total gob stopper spec with the WRC o ring gas conversion. in a nut shell no need for head gaskets. Rich from launch originally comissioned its build but due to business and time constraints just hasnt got the time to dedicate to this build. to that end i bought the engine off Rich and started the process of stripping down the bits to see whats what. for those interested the spec includes.
