Will be installing my new LT headers this weekend () and am wondering if i should use some FMS stage 8 locking bolts? I have found a set for $45 plus shipping. The LT's are MAC with the individual style flange, not solid like BBK. I have read others just use stock type grade 8 non locking bolts and retorque them after a couple heat cycles and they are fine. My thing is I am switching to the LT's because my shorty headers are consistently leaking and I can't stand that sound. So I don't mind spending some extra coin if it will help in the end.

Your thoughts are appreciated!!!
