Part number for exhaust studs, 22re
Got a brand-new Engnbldr Street RV head sitting in my living room, and I want to put all new Toyota studs in it for the exhaust.
Having a hell of a time finding the right Toyota part numbers for them though - can anyone help?
Also - it looks like the upper studs should be longer to accommodate the air injection manifold, is that true?
Thanks!

IMO the LCE ones are better suited to headers which have a slightly thinner flange on them.

The factory exhaust manifold studs have a shoulder in the center that can interfere with proper header tightening. For better holding strength, our 10mm x 50mm long, heat treated plated header mounting studs are stronger than stock. Includes: eight studs, serrated locking nuts.

I just ordered the TG header (on sale btw) and spaced on getting a new set of studs/nuts. Odd - the LCE kit shown above has all the same size 10x1.25x50mm studs. The Toyota system shows the attached pic.
It shows studs and bolts with 3 different fasteners.
Does anyone know the thread depth of either side of the LCE studs?. I have a set of new Toyota OE parts that are 10x1.25x50mm w/ lock nuts from a different project and can use those if the thread depth is similar.
Its all together still as I plan on doing the job this weekend so the obvious question of 'what came out?' can't be answered yet. I want to get a head start on studs if I can't use what I already have. The TG flange is 1/2" thick.
Any help would be appreciated.

One there is only two different sizes on the 89-95 22re's. I cannot confirm anything lower then that right now, I'd have to look it up.
Two I had no fitment issues with the LCE studs in my 87 22r.
Three that above photo shows intake manifold not exhaust manifold.
