Re: IML: Dick B's valves

["Robin Giesbrecht" <robings@xxxxxxxxxxx>]

I know what a lot of urban myths say but that should be laid to rest with 
evaluations done by  MOPAR performance magazines on big block heads. If you 
want hardened valve seats get a set of 400 heads from the wrecker. Problem 
solved. And they breath very well, better than the old heads.They are open 
chamber  so your compression ratio may go down depending on your engine but 
there are ways of fixing that.
