Realizing that 292 covers are different than 216 and 235.
That's why I mentioned the Inliners advertisement in 12 PORT NEWS
http://www.merchantamerica.com/chevyhotrod6/index.php?ba=home They make an adapter (I do not see it on the web site so call) for chevy two stud 216 valve covers to fit on a seven screw 194, 215, 230, 250 &292 heads. From what I now know is Larrowe & Sons Truck Parts in Sandy, Oregon. It also appears from the advert picture you can fit this over roller rockers !!!!
a shocking sleeper ??
but i'm still going to give them a call to be sure.
