Rick, I run my 358ci yates(cleveland) headed motor at 30 degrees initial and 30 degrees total. Its all in all the time. If it will start and does not ping, more timing is a good thing. On the total, I agree with Scottj's comments, it depends on how efficient your heads and motor are at peak power. With yates heads, 30 total is max power, with a typical FE head, they are less efficient and need more total for peak power. Good luck, Scott.
