I have a set of stock 79-85 Chevrolet 350 Heads that I am reassembling.
There are 8 washers that were inside the Spring Cups.
I need to know if they are for the intake or exhaust valves.

Thanks !!

 

the only washer i have seen were used to shim the springs back to the correct pressure after doing a valve job .do you have a picture ?

 

I don't have a pic. Sorry.
Think they are actually shims. VSI 203 THIS SIDE UP stamped on them. Located under the cups.
I got these heads unassembled. They didn't keep everything together and marked. All the springs, cups, keepers and retainers were just in a bag, so I have no idea which valves the shim's were on. And the guy I am doing this for doesn't remember. But there are only eight, which leads me to believe they were probably only on one or the other ( exhaust or intake ). The story is these heads are off an engine that was used in either a pull or mud truck.
The Valves were marked, thank god.

 

yep sounds like valve spring shims ,if they were run before with them some time's there are tell tail marks from the shims on the head's ,check the valve's for thickness on the edge of the head ,if thin and intake or exhaust seat's look ground thin they might clue you in.otherwise take them to a a machine shop and have them set up for spring pressure and stem height .
