Be warned when you fit alloy heads and roller rockers. It is critical to allow clearence. My setup allowed 2 gaskets to clear the rockers. Only when I finally started the beast on Boxing day did I find a leak. Eventually found it coming from the right valve covers. I lowered the motor 2" all it would go with everything connected. Found the supplied stainless bolts were bottoming out without compressing the gaskets.
Big job removing the rear bolts. New shorter bolts being fitted next week
