What would you all reccommend I set my timing at? The car is an 84 GT. Stock ignition system, gt40p heads, rv cam, full exhaust with shorty headers, air gap intake, 600 cfm carb with vac. secondaries, and .030 over. The guy that did the valve job on my heads said around 10 degrees would be good. I just wanna get a second opinion. Thanks everyone.
