Timing should be 24-26deg at idle 34-36deg @ max advance (a 10deg advance bushing)
Jetting 70 to 74 pri 80 to 84sec 4.5" power valve .031 shooters.
What is the 1/4 mile ET and MPH?
What is the car lacking? low rpm torque, top end power?, RPM????
What is your power goal.... ET/MPH goal from that combo?
Both the cam and the 180cc heads are small for big serious horsepower.
But it should be no slouch on the street.
Exhaust system is critical too. It has to flow to make power. Test with open exhaust and collector extensions.
The MPH from a 1/4 or 1/8 mile drag test tells the tale of how much HP it is making. (with known car weight w driver)
While I really like the Jegs/Profiler aluminum heads (If that is the head you have), I would not have used the 180cc head on this 406 motor.
(It can be improved a lot with porting)
