Td Head Gasket Notch

[zx1.9td]

hi guys im a newwbie so please go easy on me

a recently brought a 1994 volcane td

i stupidly wacked the turbo boost up to 18 psi and blew the crap outa the head gasket

ive stripped the head off but im in a delma about this head gasket notch buissness

the old gasket seems to have 5 notchies in a row then 1 notch all on its own

the pistons stick past the block by 0.76mm at tdc which to be safe i would say 3 notch gasket BUT if the head has been skimmed would i be right in thinking that i might need a thicker then 3 notch gasket ?

please help as the more i look into this the more confused i get

thanks
