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) |

the valve stems are filled with sodium to isolate the heat to the head of the valve.
you want high heat transfer to the valve seat to keep the valve cool. |
