I have a 305 that the timing chain jumped a tooth or so.I replaced the chain then the heads and intake do to bent valves.I have replaced every thing down to the cap and rotor and can't seem to get it timed right.can any body tell me what i am doing wrong?????????????????????

Make sure you put the timing chain on at TDC on #1 cylinder with both valves closed and not 180 out. This used to get me a lot when I first started working on motors. The easiet thing I found is put your thumb over the #1 spark plug hole and turn over the moter until you feel pressure and you are on the compression stroke and where you want to be to put on the timing chain. You may already know this, if so disreguard.
