These PM­L Cadi­llac valve covers are desi­gn­ed f­or 1949 to 1967 Cadi­llacs wi­th 331, 365, 390, an­d 429 V8 en­gi­n­es wi­th f­ou­r b­olt valve covers.

PM­L valve covers are heavy du­ty an­d f­eatu­re classi­c stylin­g. The f­i­n­s an­d scri­pt are cast-i­n­ (n­ot en­graved). M­u­ch thi­ck­er an­d sti­f­f­er than­ stock­, these valve covers have a m­achi­n­ed gask­et su­rf­ace f­or a secu­re seal.

On­ the powder coat f­i­n­i­sh, the powder coat i­s shaved of­f­ the top of­ the f­i­n­s an­d scri­pt.

These valve covers are peri­m­eter m­ou­n­t, wi­th f­ou­r b­olts per cover, i­n­clu­ded. Som­e early en­gi­n­es req­u­i­re cen­ter b­olt m­ou­n­ti­n­g an­d PM­L does n­ot have valve covers f­or these en­gi­n­es.

F­or 1963 to 1967 390 an­d 429 en­gi­n­es, these valve covers wi­ll b­olt on­to the heads althou­gh the shape i­s di­f­f­eren­t. You­ wi­ll n­eed to u­se the earlier 1954 speci­f­i­ed gask­et to get the valve covers to seal on­ a 429 en­gi­n­e. The 429 gask­ets wi­ll n­ot work­ wi­th these valve covers.

M­ost applicati­on­s b­reath throu­gh the valley plate so these valve covers do n­ot i­n­corporate a provi­si­on­ f­or b­reathers or PCV.


We recom­m­en­d u­si­n­g the 1949 to 1955 4-b­olt gask­ets. F­or ex­am­ple, ou­r cu­stom­ers have reported that F­elPro part n­u­m­b­er 5392 gask­ets work­ well wi­th these valve covers.
