I just finished my valve grinding on my 2.8L fiero heads. I noticed when i put them back together, the stem seal was pushed down below its groove seat. The seal should sit right at the bottom of the keepers. When i compress the spring, the keeper, i think comes down and hits the seal, driving it down. Is there a way around this? Or can i just push it up with a screwdriver or something? I sort of tried this with a screwdriver, it looks like the stem seal should be partially under the keeper, so i dont think i can just shove it up far enough. Any ideas would be great, thanks.
