I got my fancy Mopar Performance valve covers and a set of T handles. I'm not sure I set the studs properly. When I start the engine the vibration makes the assembly come loose.
I put the studs in finger tight. I am afraid to bear down with the T handles because I don't want to ruin my valve covers. Is there a "torque spec" to tell me when to stop?
I am not wedded to the T handles, they are for convenience of installation (motor home, beats crawling around underneath to get the outboard ones). If I junk them, what's the best bolt option for a 1976 440 with 452 heads and Mopar Performance valve covers?
Thanks.

Hmmm these did not come with washers, that's one of the reason's I'm concerned about ruining the covers. I'll consider testing that. Use a flat washer AND a lock washer.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I had some on my 800 hp wedge and on the dyno we watched them spin counterclock wise at higher rpms. It was harmonics

Thanks. I'd try lock tite, blue and maybe a lock washer? Might have room for a washer if you try a AN washer which is smaller than a reg washer. That would help protect the valve cover from the lock washer. Make sure the valve cover are not interfering with the intake manifold too.

I always use a AN size flat washer under any bolt head I use on aluminum parts, unless the bolt has a flange built into it, to prevent wear, digging into the part and marking up the aluminum I can't remember using a lock washer on any but why not
