350 valve stem seals

[Chrissy]

Hello! My name is Kristjan. I was brought a 1970 Pontiac LeMans. Need to rebuild the engine. I got stuck with valve stem seals. When I took cylinderheads apart I found all the seals broken to pieces. Bits of plastic (old rubber) and some metal rings. The exhausts did not have any seals apart from the small o ring. We ordered a rebuild kit, there were seals inside with metal rings that looked the same, but the seals did not fit on the guides. So now I don't know what kind of seals do I have to order Thank You all!!!

My apologies. I did not know that. 16 umbrellas it is then. Thanks!

Is this ok? Two seals, o rings and umbrellas?

yes, that is fine. Not sure what else you are doing but if you intend to do a camshaft change you may want to consider screw in rocker arm studs.

We just want to rebuild the engine. With oem camshaft and other stuff. Ordered a kit from summit. Basically everything is going to be replaced. Block was drilled, crank is grinded and next week I'll start putting it back together. Not after high powers. I have to thank you again .
