Yeah thats what I was saying. I guess ill stick with some ported windsor heads instead.Edbert said:I think you are talking about the Chebbie valves from their 5.7L. They can be easily fitted into the 351W heads by a competent machine shop, but you do NOT want used valves.
BC_Ace said:Why not used valves?
There are three places where a valve will wear. The seat, this can be ground and polished for a good seal before being re-installed. The retainer groove(s), IMHO once there is wear here they are trash. But they can also wear on their shafts where the oil seals are. In the old days of leaded fuel the lead served as a lubricant, but many an old engine was run with unleaded gas and caused excessive wear. This could be the source of your blue smoke too.BC_Ace said:So, would you think this could cause my engine to smoke(burn oil) when I punch it?
My engine has about 3000 miles on it since rebuild, and I'm running used chevy valves in my stock 289 heads that were machined and assembled by an experienced shop. Since the rebuild, I've replaced the valve seals, with no success.

If you were having a romantic moment with your significant other, would you use an new condom or pull out the one from last night?
Would you drink used beer?
That's good! Most decisions can be this simple.
