Hi all , i'm putting my heads from a 95 wrx on a version 3 sti block , what head gasket thickness do i need /is best, or how do i work out what thickness i need ?
any help much appreciated , thanks

 

All depends if the heads/block faces have been skimmed in the past and if you are using standard pistons/compression height
If they are to factory spec,then go for the STi V3~4 MLS head gaskets (1.60mm thick).
