anyone can help me?

for high boost i would get a bigger once. i have similar spec´s and use the HKS 2.0mm with 2.1 bar of boost...

 

[tenfoloten]

with 2mm hg there is much more weak in not turbo phase,from 1,2mm hg..or are similar?

 

[pulsarboby]

think youll be best off using a 2mm gasket! at that boost level you want to keep the compressions down to enable more reliable running.
your likely to have head and gasket probs with a 1.2mm at 1.8+

thanks a lot for your reply..
on tomei catalog the tomei 1.8mm do 8.1:1 compression
and hks 2mm do 7.3:1..why is possible?

hks hg hasn't got all holes for water passage from block to the head
