Timing will depend on other factors you haven't mentioned, but typically we find they like about 33 degree's total. I use NGK non-projected tips in a heat range compatible with the application. I'd start out with a -7 plug on a street car.

It really makes me wonder why some of you guys need so much timing. What is so different about your combo with the same identical head that requires it? My guess is it's a Band-Aid to cover up other issues you may not be aware of. Now, before you chastising me, I've put many Indy heads on small block combo's and I've never had to run more than 35 degrees to make the best power. as far as reading your plug for timing, perhaps you're just running the wrong plug.
Okay, flame away now.

Are the engines pump gas?

Little different animal, but I put W5 heads on a 11.8 flat top shortblock and they ran best at 40. Turn it back to 36 and it would kill exactly a tenth in back to back passes. Throw same heads on a 13.3 dome shortblock and ran best at 32
