Im in the process of swapping engine blocks both 2000 4.6 2 valves after im assuming spun a rod or killed my main bearing. Question is the old engine had pi head/intake and a bunch of nice bolt ons so i want to transfer everything over to the new block but i need a bit of guidance on what to do about installing the heads properly.The notion i had was setting both blocks TDC and using an retention tool to hold the cams in place. would that work or am i heading for disaster? ---

A cam retention tool only works if the heads remain on the block. ![image](https://global.discourse-cdn.com/cartalk/original/3X/c/f/cfb970bc5198b67c53951243ecd25b619f0032bd.jpeg) Tester ---

OHC cylinder heads from an engine with bearing failure will need to be inspected for damage and cleaned (hot tank) to remove the metal debris from the galleries. ---
