10.2 : 1 compression 360 at sea level. Options?

I do have an O2 sensor and gauge, and a high flow water pump. Will look into a new fan and shrowd and possibly a 6 pack hood scoop to get cooler air intake.

So you guys think I'll be safe running 93 octane gas with 10.2:1 compression and iron heads, with 280 duration cam assuming I can keep it cool?

I've got pretty loud exhaust. Is it possible to not hear the pinging? Is there a good way too test?
