you didn't set it to TDC correctly. factory service manual is your friend.

To check your cam timing, first disconnect the ignition coil wire, remove all the spark plugs and remove the valve cover. Have someone tap the starter while you have your thumb over the #1 spark plug hole. Once you feel compression, insure that the block timing pointer at the front pulley is pointing to the zero mark on the pulley. Remove distributor cap and insure that the rotor is pointing to #1 firing position. The #1 piston is now sitting at TDC compression stroke. Remove the upper and lower timing covers. Now look at the lower timing chain for the chain mating (silver) mark which should be at the crankshaft sprocket gear mark. The top end of the timing chain mating (silver) mark should be at the large idler sprocket gear mark. The upper timing chain mating (gold) mark should be at the small idler sprocket gear mark. The other two chain mating marks should at their cam gear marks.
