Surfrjag Posted December 14, 2012 Report Share Posted December 14, 2012 Can you tell us squish or cranking compression? Quote Link to comment Share on other sites More sharing options...
Alba Racing Posted November 12, 2013 Report Share Posted November 12, 2013 Shops including us have been milling banshee heads for many years with no problems. With 20cc domes your banshee probably had about 150psi compression. If your stock head was machined properly it should have about the same. Hopefully who ever did it cut the domes properly instead of just milled it. Like surfjag says squish and compression are everything. You need to check it.
