i have a carbed 85 gt 302 new edelbrock rpm heads,new gaskets on heads,intake carb,,its running rough motor shakes bad...i put timing light on it and still rough...i sprayed carb cleaner n starter fluid around intake n carb to see in vacu leak n no results...i have a new ford hei set up.....i put a vacum gauge to it and needles shakes bad from like 15-18 back n forth fast.... not sure any sugestions when i rev it it smothes out...

 

If I remember a shaking needle at idle is a sign of leaking intake valves.?????
