this on a forced induction application.
With FI on an H22, you really have to worry more about the block then the head.
With stock internals you should be able to safely cram 6-8 ps1 boost without worries.
If you want more than that then I would work on the internals.... i.e. resleeve the block, forged pistons & rods.
