A dead cylinder could be a number of things. Did the cylinder have compression before? Does it have compression now? Were the new heads in good condition you should be able to see a bent valve on a head. If the heads were in good condition and the cylinder was in good condition before the swap there is a chance that the valves or 1 valve is to tight on that cylinder. Run a compression check on the suspect cylinder as it sits. Than loosen both valves on the cylider and check it again. If the reading goes up after you loosen the rockers than they were just too tight. if no change than either the valve was bent before you installed the heads or the rocker was over tightened and when the piston came to top dead center it bent the valve. Good luck

may be a plug or wire to swap them around see if the miss moves to another cylinder. ive bought brand new and ran across bad plugs/wires..
