Lt1 roller rocker HELP please

[Juztin]

So I found a brand new set of jegs roller rockers for a sbc for $85... can someone tell me if these will work on a stock lt1? I'm somewhat new to these engines. Do the stock lt1's have 3/8 studs? I appreciate any help I can get with this. Tia!

My understanding is stock lt1 needs self aligning rr's and poly locks will not clear stock valve covers.
