oldkili98, at this point your best bet is to remove the rockers so that you can turn the engine without binding. Then you can get the engine to TDC @ the Crank, then line up the cams. Once you do, when you start to replace the chain, if it is NOT TIGHT you may need to ADVANCE the cam(s) slightly to get the chain on properly so it's timed right. Then you will most likely have MUCH more slack in your tensioner which is currently losing slack due to the valve/piston interference. I got lucky when I did my car's timing belt and although the cam jumped on both banks and I couldn't turn the engine, I guessed where the cams should go, and after turning the engine by hand 10 times because I couldn't believe my eyes, it turned out my timing was DEAD ON by lucky guess.
