[Public-List] Head mounting liner boat

[David A. Bardsley]

   I removed the original head over the weekend and the four square headed
   SS bolts have an aggressive self-tapping thread.  My instincts say
   there is a large block of wood or GRP filling the void between the
   liner and hull, but without performing unwanted exploratory surgery I
   cannot say for sure.
