    Guys I picked these up the other day along with an original 302 air filter assembly. As with most stuff I seem to buy online as of late the sellers seem to take very directed images to keep the flaws from being questioned. But these go a bit farther than that. They almost look fake. Look at the breather ports. Not only are there no baffles, the ports look like they are deformed from a copy of a real one that still had the baffle in it? They don't appear to be blasted, it's like they are raw fresh castings and not really good ones. But I'm looking for opinions before I call the seller out. 20200430_102801.jpg 20200430_102738.jpg 20200430_102721.jpg 20200430_102717.jpg 20200430_102709.jpg 20200430_102656.jpg 20200430_102801.jpg 20200430_102738.jpg 20200430_102721.jpg 20200430_102717.jpg 20200430_102709.jpg 20200430_102656.jpg

    Mike - honestly, they look like a set of used originals that had the baffles removed, were cleaned, (lightly bead blasted) and just did not have the baffles re-installed. Just my opinion, but if the seller represented these with the baffles or used words that would indicate the baffles were not missing, Yeah, I'd go back and ask for a refund...at least on the valve covers.

    I paid $125 for them so I'm not out much just feel like the baffles need to be in there before being used. Can the baffles be purchased separately?

    I've never seen the OEM baffles for sale although I can't say I ever looked for them. You'll have a hard time attaching them even if you found a pair of baffles. At $125 for the pair, you got what you paid for. These covers that are not late model repo's in good condition regularly sell for well over $200 and the covers without the cast in drippers command much more.

    Maybe the baffles from the stamped steel covers can be used? Easier and cheaper to find.

    I remember dimpling or removing baffles back in the day for roller rocker clearance but usually the drippers needed help too. I remember using rubber push it "baffle grommets" from the speed shop but they were a little big for the hole [this was the 80's and the cheap transdapt chrome covers didn't have baffles ] that was the fix for those.been 35 years bit foggy but I guess you could use those "baffles to keep the oil sucking/splattering to a minimum! Later Steve!!

    Find a junk set and JB the baffles in. I don’t understand why some knuckle head would remove them to blast them.

    I would agree. I think I still did just fine. They are in pretty nice condition overal. Just wish they had the baffles in them. It appears based on the numbers in them that they are in fact 1970 valve covers. So I think I'll just let the baffle issue go. I got my money's worth.

    The casting numbers inside will tell you what year or years they are. There were about 4 or 5 different versions of these covers with different numbers. There are posts here on Nasty with pictures and those numbers to identify them.
