I know Jake suggests tossing these, but unfortunantly Im rebuilding a set of heads. Id like to keep them stock, but Im more concerned about longevity.
Is there anything that can be done to improve thier function? Cryo? (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) |

Just a few observations:
1. I have noticed that Jake always is comparing the re-use of an old sodium filled valve to replacing it with a new stainless valve. I think we can all agree that 100K+ mile valves should probably be replaced. The question here should be new sodium vs new stainless. 2. Lots of people trying to correlate valve material to head temperatures. The valve material should have no real effect on head temperatures. The reason for the sodium in the valves was to keep the valve itself cooler - not the head. Demick |
