II, 2.9L, 4X4. PUT IN HEADS & GASKET SETS, SET TIMIMG TO PREVIOUS 800RPM. STARTS GOOD BUT AFTER A BRIEF WARM UP LOOSES SPEED OR WON'T PULL & RPM DROPS TO 500. CAN'T FIND THE SPECKS ON VALVE STEM SETTING. WONDER IF THIS COULD BE THE PROBLE

I wonder if the valve stems need adjusting and can't fing the specks on a Bronco II, 2.9L. Has no power.

Check the valve and ignition timing if its correct-start here
