pictures would help.
yup.Looks like a rebuilder's/remanufacturer's stamping to me.
I stamped my block with my initials to make sure I got the same block back. Looks like your stuff has been at the machine shop before you owned it.I need help,can't find anything on my block or heads on my 2005 GTO both have LBM stamped where the GM casting should be I've Google search the hell out of it for the last 5 months and still can't find anything any help would be appreciated thanks guys
LBM Block #VF050040964
LBM head 122332∅A∅2329∅51
Thanks so here I'm hunting a builder LBM but more than likely it was a previous owner,but then the VF050040964 on the block and then that big long number on the heads 122332∅A∅2329∅51I stamped my block with my initials to make sure I got the same block back. Looks like your stuff has been at the machine shop before you owned it.

Definitely cast it in real thick nice letter H∅36 2 22 definitely not etched it's casted in the aluminum and based on the V/springs and the the rocker arms these are LS3 heads I know it's crazy I just can't understand why nothing is or nothing has original GM markings that's what's throwing me off on all of these things trying to cipher what H036-2-22 actually means is like a needle in a haystack I think without knowing or first figuring out what that block number and the number etched on those heads come back as I guess but as always I do appreciate you guys any kind of help like this is appreciated I pulled my hair out for 5 months on this trying to figure it all outthere should be a 4243 in the center if it's the original pair of 243's that have been worked.
are the numbers stamped or machined, or are they cast-in?
it pisses me off when shops do that 💩 . i mean they can go ahead and stamp or machine whatever they want, but don't get rid of the original casting numbers.
Sorry everywhere else I posted without the zero like that would say the opposite of what you just said is that a zero or an O so now I know the flavor of this site I won't do that no more thanks for looking for meare you sure it's not 035 and not 036? the H might be a number, just hard to see.
and stop using ∅ for zero, please. it's confusing.
a few of the other long numbers you posted look like they are factory markings, i'll have to look tomorrow.
