with that high of compression you need to change your head gaskets to a solid copper and have the block O-ring'd. I used to run that compression and was using standard fel pro gaskets, and I was melting the cylnder walls and heads. here are some picks of the damage at only 8 lbs of boost, you can see the dips between the cyl

ouch. that head and block are done.
On anythign greater than 9:1, the ability to control teh thermal becomes paramount. Thermal management is what lets turbo engines live. I'd consider methanol or water injection.

Nope its called drop the compression. The new motor is a nice low 7.6:1. And I was able to have the head and block welded and I rebuilt it . and it has been a year now on an NA application.
