Subject: Pietenpol-List: Re: Continental Valve GuidesThanks Gene, but that's the interference fit between the valve guide and the borein the head. ie: The guide should be .001 to .0025 larger in O.D. than thebore in the head. The head is heated to expand it, and the guide chilled in thefreezer prior to pressing the guide in, making for a TIGHT fit. I can buy guides using the bore diameter's I need, but the places I've called onlylist them by oversize (+.010, +.020, etc) rather than by actual O.D, so I'llneed them to mic what they have so I get the right size (or perhaps I shouldsay oversize)Thanks,Dave in Panacea> > > > > TABLE OF LIMITS Min.
