to pull the assy down. Before I do that are there possibilities of headers
/ muffler pipes touching the frame causing a resonant vibration ?. It feels like around the central part of the car. I checked out weather these assemblies are balanced when you get them and they are but I also heard that you should balance match the flywheel to your stock one. It does not seem like a practical thing to do when your car is on the lift waiting for the assemblies are to be done. I really need some help here from anyone who had a vibration problem and found it to be headers or something.
In short the vibration problem is not speed sensitive or acceleration sensitive which I first thought. it is purely RPM sensitive clutchin or clutch out.
