PC seals for SBC exhaust valves

[Clone TIE Pilot]

I used PC seals on both intake and exhaust along with the little O rings. You will want a set of picks to push the O r7ngs inyo place while the spring is compressed. Excess oil dripping down the valve stems will give a false rich reading to the O2 sensor besides fouling it and the spark plugs.

Thank you for that. I tried to put the O ring on then the spring. This is a very hard job. I guess I better tear it apart again.
