Inliners International Forums General Discussion Engines HELP! Threaded insert for head bolt question

Thanks guys. Yeah, other board I am on is also saying the 3/4" version so that's the way I'll go.

I am using studs. The red sealant/locking stuff on the insert, once cured is claimed to seal up to 6000psi. Supposed to be good stuff. Never been a real big fan of JB Weld for stressed applications.
