What's the Max Timing Advance on a Type IV?

[Wendell #527]

I have a 2771 type IV with a Teledyne oil cooler (Oil runs at 180f). Compression is 8.75:1. Regular distributor with Compu-fire ignition. What should the total advance be? Also what should it be if I bumped the compression up to about 9.5:1?

Thanks

10 degrees static and 30 degrees running and advanced. My 4 seater is 10.25:1 and that's what I run mine at.
