Hi, with Stoneleigh coming up next year I am making a list of stuff to look out for, one is a head gasket set, my car is a mk3 gt6, engine no. KE/20055-HE, although the head is stamped up as pic 1. 218225
gearbox no has been overstamped GR 901347 as pic 2. just shown that for additional info.
would anyone know if it would need the recessed head gasket or non recessed, or how can I tell? any advice appreciated.
p.s I blew up the gearbox pic and original no looks like WM 36826
