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) |

I agree that the longer duration probably acounts for the lower head temps. But, that heat has to go somewhere and I can only see 1 place and thats out the tailpipe. I wonder what exhaust gas temps are like. I wish I had that info. Also with the exhaust valve off of the seat more wouldn't the valve soak more heat? I wounder what the steel alloy was in the stock valves and how it absorbed and dissipated heat. If it wasn't as good as SS at dissipating heat that may narrow the difference between SS and sodium filled valves.
