went to put my finned thunderbird valve covers on in place of steel and studs on my 292 won't reach by about 1/4" or so as they are flush with the rubber washer - Eickman's book shows page 94/95 two different length 3.86" 1961 & up and 4 1/8" which is what it looks like I need --does anyone make these appreciate help Laroy

I bought the ones Tee-Bird.com sells along with the Acorn Nuts and they were still marginal as far as length.

  

yes, you can buy them from most t bird parts places, tee bird products, larry,s.

appreciate the help looked at a couple sights and noticed I needed the grommets without the washers 4 the aluminum covers again thank you

If you can come across them, the valve cover studs for the Ford LYB 302/332 truck engines are the correct and longer length for the Thunderbird valve covers. The rocker arm stand supports from these same engines are also iron and if turned upside down, they are also a perfect fit on the Ford Y-Block engines.

The Long and the Short of it.

I ran across this the other day and it is somewhat pertinent.

In the CTCI Restoration Manual there is a note on valve cover gasket thickness that may have an impact on tightening the nuts. (p. 167)

"... the original type rocker cover gasket B4AZ-6A506-A. It is made of 1/4 inch thick cork painted argent (silver). Thin after market gaskets may allow the rocker arm cover or acorn nuts to bottom out before a complete seal is achieved, resulting in oil seepage from the rocker arm covers."

This could cause some to over torque the nuts in an attempt to stop leaks.

Torque is listed as 2.0-2.5 ft-lbs. Probably more critical with the aluminum valve covers. Or "aluminium"
