I am fixing to obtain a z6 block with y8 head combo that has already been put together and I just got done reading Benses article on using 9 z6 head bolts and 1 y8 bolt . Do you guys think that this will cause premature head lifting . I plan on boosting anywhere from 7-10lbs . I am going to say that they used all of one kind and they didnt split em up . Just lemme know what you guys think might will happen .

Thanks

 

Just go ARP if your scared.

 

any more ideas or comments ??
