Hi,

My Haynes manual says that the height from cylinder head joint face to face for head bolts is 3.34 inches (84.9 mm) for a B20E and 3.42 inches (87 mm) for a B20F. The compression ratio is 8.7:1 for the B20F and 10.5:1 for a B20E yet the power difference is only 5 bhp and 7 lbs/ft torque. Is the small power increase worth the hassles of a higher compression ratio? You may end up losing that power increase if you have to retard the ignition to prevent pinging... Gas flowing might be much more useful.
