Getting worried-----

My precautions would be to:
- Make sure the cam is not advanced beyond the ICL spec'd
- Push the ignition timing forward with caution
- Make a check of your true compression ratio; if you have engine data on heads, combustion chamber size, any head milling, head gasket, and other factors that effect CR, list them here

My comments involve having a mild duration cam and high Static CR; your dynamic CR may be a bit high and it might be more prone to detonation. Keeping cam advance under control and keeping the ignition advance managed will manage that situation. And your true CR is likely not 10.5:1 anyway, if you are using stock parts and Egge pistons.

So this is mainly a 'be careful' comment. We went one step large on cam choice even with AL heads and a true 10:1 SCR just to stay comfortably away from 'detonation-land'.
