[Roadsters] head bolts

[jamie tousignant]

 hey anyone have experience with head bolts and washers  to take up the
difference in a head?after being surfaced
 i have a 2litre that has compression loss after less than 1200 miles on it
since rebuild  of  and notice the builder used washers
under the head bolt nuts it was  5 on one and 4 on another  down to 2 in the
middle  which i believe would cause the  pressure to be different
when being tightened  ? has anyone had their studs threaded longer to remove
the need to do the washer trick?
i know you can purchase shims for the towers to take up the slack if needed
but  am struggling to work out a solution
for this problem
