Default HG Thickness help needed

I will be using an STi8 short motor and STi5 heads in my V5 uk Turbo. Which head gasket do i go for and what thickness?

Currently running 370bhp/350ftlb on 18g, 550cc injectors etc

Thanks

0.6mm would be the norm.

You need to calculate which thickness of head gasket will give you the correct compression ratio.

If the block or heads have not been skimmed the compression ratio should be standard.
