Trick flow rocker shaft studs

Hi all,
Just wondering if anyone has a set of the small block TFS-61400613 rocker shaft studs hanging around that they could measure the overall length of for me? Or does anyone know the length of these studs?
I contacted trick flow tech department last week to ask them for the overall length as they don't list it on their website, but yet to get a response back from them.
My PRW rockers came with studs but they are too short to accommodate my geometry correction kit.
Would rather run studs instead of bolts on the alloy heads if I can find some the right length.
Cheers,
Ted
