Yes, like what thesals said, adjust your valves. You can do it by another method. Take your pick.

Ok, when looking at the engine bay from the front of the car, the cylinders on the right (driver’s side) are numbered as follows. The most forward is 1, then 3 then 5 and then 7. On the left ( passenger side) the most forward piston is 2, then 4, then 6 and then 8.

Turn the engine with the plugs removed (if you can rotate it without removing them, then that is fine) but do not rotate with the starter, just in case you already have a few valves adjusted too tight.
Firing order is 18436572

Valve adjustment should be done in such a manner so as the rocker just barely snugs up with the push rod, then add half a turn. The push rod should still turn freely after the adjustment is done, so DO NOT tighten the rockers! You should feel a slight difference in resistence when rotating the push rod before from after the adjustment is made.
Rotate the engine and watch for the #1 exhaust valve to open half way, then adjust the intake valve on #1 and the exhaust valve on #6.

Next, rotate engine so that the #8 exhaust valves opens half way, then adjust the intake valve on #8 and the exhaust valve on #5.

Next, rotate engine so that the #4 exhaust valves opens half way, then adjust the intake valve on #4 and the exhaust valve on #7.

Next, rotate engine so that the #3 exhaust valves opens half way, then adjust the intake valve on #3 and the exhaust valve on #2.

Next, rotate engine so that the #6 exhaust valves opens half way, then adjust the intake valve on #6 and the exhaust valve on #1.

Next, rotate engine so that the #5 exhaust valves opens half way, then adjust the intake valve on #5 and the exhaust valve on #8.

Next, rotate engine so that the #7 exhaust valves opens half way, then adjust the intake valve on #7 and the exhaust valve on #4.

Next, rotate engine so that the #2 exhaust valves opens half way, then adjust the intake valve on #2 and the exhaust valve on #3.
