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) |

...and for a fun experiment you can do at home! Cut open the old liquid sodium filled valves and pour that liquid sodium down the sink! Your kids will love it! Your wife... Well, not so much. She will be needing that new kitchen now, thank you!
Actually, I agree. The head rebuilders who do mass quanitity not quality are going to toss them and use new valves that are not sodium filled. They might give you the same arguement about 30 YO technology but what it really boils down to is that $55 per valve. Performance head rebuilders might use something different because they are working with different set of goals. If you don't want to rebuild those heads every few years you probably want to use sodium filled valves... |
