i finally put on my 2x4 setup today, it works great and runs strong, to bad the linkage dont work yet and the trans is shot. i'll get to fixing both before next year. i was looking at a torn up pair of factory aluminum valve covers i have. i listed them on ebay because i'm probably never going to fix them. i'm looking for a replacement set now. i seen a set on ebay and they had an extra hole than mine. how many different finned aluminum valve covers were made by buick, and what was the differances for each application.
