Small Block & Big Block Chevy Specific - Flat tops or domes for a 300 shot????

I'm thinking about doing a 300 shot, but should I run flat tops or domes?? I was told I need more compression to run the cam I have which is 248/258 @ .050. Right now it's 11.1 with .125 dome. I was told nitrous likes flat tops cause the flame travels better, but everyone has there own opinions. What would be the best way to go????

Nitrous seems to be more effective with flat tops, the flame front travels faster.

11:1 should be plenty enough compression for a 248/254,i'm just running 11:6 with a 259/267.

I'd go with the flatter piston top due to issues with flame speed when running popups. Also, don't forget, your DCR shoots WAY up with a shot that big. The last thing ya want is still burning NO2/O2/Fuel mixture when the exhaust opens.
