Don=E2=80=99t know if it=E2=80=99s my trick or if everyone does it but...=20=

Once I=E2=80=99ve got the liner landing as clean as I can get it, I use a ol=
d liner as a hone and by twisting is back and forth with some valve lapping c=
ompound, get a nice shiny ring on the block mating face. Clean it up good an=
d then use your sealant of choice.
