Valve Seals

[Rob M.]

I am looking to replace the valve seals for my '66 327/300 and I would appreciate any recommendations for new valve seals - manufacturer, part number, cost, etc. Thanks in advance.

I just installed a set of Fel-Pros which are available as a kit from virtually any auto parts store at $10-15/set. They look just like the originals - except they're not rock hard or falling apart.

Rob,

Many brands and different styles....you may get numerous opinions. Go to the person(s) who builds engines for a living, see what they would recommend. All valves seals are not created equal..

Patrick and Michael,

I appreciate your responses. I am sure that there are many opinions and not all valve seals are created equally. I will ask an engine builder that I know, but thought the collective wisdom on the board would guide me in the right direction.

Thanks

I'd suspect that "most" of the plain-looking O-ring type are made by a small number of companies, and the rest are just repackaged and sold. That's why I went with the Fel-Pro ones. Well, that and I already had 2 sets on hand that came in engine gasket kits.

The stock-type seals will work well IF they are properly installed and with metal shields also installed. Of course, for these or any valve selas to work properly, the valve guides and valve stems have to be within tolerance.

If you want to improve sealing, also install positive type valve seals on the INTAKE valves. Use GM #460483 or equivalent.
