I've decided that i'd rather have a crappier flowing head with quench for a nicer, more efficient engine than say, a possibly more powerful engine, thats less efficient, with an open chamber head and no quench.

"Possibly more powerful....that's less efficient" Not to bash but sounds like an oxymoron.

With the variance on combustion chamber from cylinder to cylinder (w/open chamber), bowl & template porting, exhaust valve update to 1.74, cubic inch size considered, using a flattop piston, and ultimately good quench................I'd be surprised to see an open chamber combination actually make better power. And then it would only be in the upper rpm range.

Not that anyone would ever waste the time to do an actual build/dyno comparison.
