I would suggest 25-28 degrees with a total dwell of 32. 34-36 might cause the timing too be just a bit retarded. You want them advanced a little more than that. Try both ways and see how the performance is. I used to spend my life doing these on Corvettes.

Like Junket says, use a dwell meter and bridge across your solenoid, using it as a remote starter switch. Keep the ignition key in the on position and measure the dwell. Using a feeler gauge is too subjective.
