compression with 91 octane
this guy from import builders told me i dont need to sleeve when running 12.8 compression as long as i run race fuel to not detonate. i want to run 91 octane so he goes u can do that on 12.5 but i dont want o risk it so im gonna do about 12.1 with 91 how does that sound to you guys. also does anyone of u know if a company makes 2 layer head gaskets for a b20 block

1. you exceed the bore that the stock sleeves can support
2. you exceed the HP that the stock sleeves can withstand
