... the coarse end of stud (lower aka head end) has 14 TPI and it's 7/16" aka 7/16-14 ... it's like that no matter how the upper (rocker) end is sized.
I'm not even gonna try this late V6 rocker retrofit into sbc ... it ain't worth the time or expense ... Not for me. And, No, a hydraulic lifter cannot compensate for all those variable heights/lengths/thicknesses encountered when building motors ... more PR lengths and/or ability to shim pedestal heights required.
** and this here tempest in a teapot just triggered an old memory. We built a relative oddity in the CT world. A brand new, one-off straight rail Super Late Model pavement chassis with a 5-star Dodge nose & bumper cover and a true Mopar small block. The car owner insisted on Dodge power. I don't recall which sbm motor that was (perhaps 360A) but it has OE NON-adjustable valvetrain. For those hardheads that insist on that Mopar motor, the aftermarket (perhaps Mancini) offered a conversion kit to convert its NON-adjustable valvetrain into a Fully-adjustable valvetrain. I recall it wasn't cheap. There were some rather smart, experienced motor guys (including a top-shelf T&D maker) involved with that project. If managing that piece with a NON-adjustable valvetrain were so simple; it would've remained so ... It Did Not! And yes, I recognize sbm not same as sbc; but not so very different either.
Again, interesting concept, 'though not altogether new to me; but not gonna bother with it.
