cranking compresion ?
got my car back together. had a reciever groove put in the heads to match the oring in the block. they had to weld up the water holes and mill them. they went from 75cc to 70cc. the head gasket i went from an .062 to a .043. the cranking compression has gone up from 90# to 150#. does this seem correct going from 8.25:1 to 8.86:1 ??
