sr20det apexi metal gasket reuse with no final head bolt torque?

[R3cK]

hi there

ive already put the head on with a 86x1.5mm apexi gasket
and i did all the torques from a - d
so only the final torque or 90° are missing.

question: i have to put the head down again.. is this possible with the same head gasket?
if yes, do i have to start from the beginning or just do the steps d, e and f (second 90°turn)?
