Roland that's him, drove my self crazy trying to think of his name, if he still has any the 350 covers were $85 iirc
Did you get what you're after? I have a set that's just laying on a shelf in the shop. Seems like under $100 repop is a pretty good deal tho'.
CARS Inc. bought all of the remaining inventory when Poston went out of business. They still have these valve covers - AVC455 on page 5 -http://www.oldbuickparts.com/pdf/catsky/catsky.pdf
