As Kharma would have it this once again became a wise choice. Since the engine was on a stand and I planned to completely strip it down to bare metal for a clean and long lasting paintjob in the correct ford blue I decided that also warranted all new gaskets and to paint every part seperately since it would all be taken apart anyway. The engine had been refreshed 6 years ago when the CAM was upgraded and ran perfectly but as it turns out the timing chain had some slack so I chose to upgrade to a dual true roller timing chain while I was in there. This is the new one installed.
