its already got head bolts for it done some researching and found out that the head was over shaved so the sleeves ended up sinking in, f***ed up hard so i thought about it.... and i've come to the conclusion that the only way to fix the problem is to replace the block (cos of high compression ) i might loose compression but at least ill save headgaskets... and i might just take it the only one that knows the motor inside out...DD
