GMC V6 Valve Cover Info Needed

[DPowers]

Looking for verifiable info on these valve covers. Have only seen them with GMC stamped. These are stamped V6 only. Diesel? Industrial? V12?
I looked on 6066GMCguy.com and couldn't find anything there.

From the 6066 Archives:

> In 1972 GMC V6 valve covers had "V6" stamped on them rather than "GMC" that had something to do with all GM engines being corporate engines rather than being individual to each division. By 1973 the GMc V6 line of engines was incorporated to Chivy's medium duty trucks which were assembled in GMC's Pontiac Michigan Plant, nothing but GMC trucks rebadged as Chivy's and that also was true for bigger trucks 7500-9500
series in preceding years. Also in 1972 Oldsmobile losts their logo on it's V8's valve covers, probably the GMC 637 V8 as well in it's last year of production. Pete Chronis Northern Cal.
