Adjustable cam pulleys

[Roga]

Is there any real advantage to fine tuning your cam timing?
I ask as I can get a set of adjustable pulleys and I am wondering if is is worth giving it a go........
Thanks

If you ever mill the heads or block, or change the compression of the motor by increasing/decreasing the head gasket thickness, then adjustable cam gears are the only way you'll be able to maintain the cam timing.
