Re: domed vs flat
What Marv D said. Flat or dished has it's advantages over domed at the same compression, but you can only make a chamber so small. Too small a chamber kills the flame travel too. Some designs work better with a big chamber and a dome. BBC is one of them, that's why all aftermarket heads are open chambered. Now a SBF works really well with a dish and a small chamber. Clear as mud huh? lol
