?valve stem seals height 853 heads I purchased some non GM unused valve stem seals from a member they are new
however they are'nt color coded like the GM seals.
I cruised by the dealership and took a close look at GM seals I observed exhaust and intake seals have differnt diameter holes think I can figure out which seals goe's by fitment.
My concern is the height of my none GM seals are all the same height the GM exhaust seals are taller than the GM intakes.
Thanks

what is IIRC?
when you say PRC springs new were all identical are you referring to the height?
if yes I'm curious why the GM seals are differnt heights? I'm still using stock GM valves.
the holes that the valve stem slides on are diffeintly differnt (differnt size holes).
BTW I like you'r choice in 205s w/ the matched cam.

I bought my PRC EHT .675 springs brand new, and all the valve seals were identical, height and hole wise. Do you by any chance know the part numbers or brand of the seals you got?
Thanks! Yeah, the 205s and the 224/228 cam is a damn near perfect combo IMHO. It makes power like a big cam, with the driveabilty of a small cam.
fel-pro #ss 70945 premium VITON seals $20 autozone, oreilly ,,,,,,,etc exhaust brown, intake black . If You look closely to a GM front or rear seal it has fm on it which stands for Federal Mogule and they own fel-pro so the factory valve stem seals may be fel-pros they look identical .
As far as the height , measured from the top of the spring seat to the top of the seal .712" to .752"

Anybody have some new 1pc seals they'd like to trade?
...and I think the oe seals were made by US Seal or something like that... but who knows, could have been multiple suppliers.
