Maybe.
They are also #714 heads that are the same and 163 and 593 that were used up leftovers.
Mainly though... it doesnt matter when it wont run.
OP. Check for a pulsing 5 volts when hooked up and cranking over at the cam sensor/distributor plug/harness...orange wire I think. If it's not showing a flashing 5 volts... its bad.
Might also be the coil. Sensors usually just stop working... while coils will fizzle out, come and go...so to speak.
