With the "V6" stamped valve conversion 72it was one fits all that eliminated stamping two separate type of valve covers

Sorry O meant prior to 72 Chevrolet trucks using the V6 had blank covers with the High Torque sticker.:pullinghairout:

Re: Before & After

I'll buy that! I remember seeing 'V6' valve covers on a Chevy, assumed it was a '66 or '67. Then again, maybe it had a new engine somewhere along the way.

I knew a guy years ago that had a 1971 GMC TDH 3301 'baby' New Look transit bus with a DH478 in it. Valve covers were stamped 'V6', but the right side one had the oil filler cab right at the front. Never saw that valve cover before or since.

Now I am extremely jealous right now. That thing will be a beast.
