I have a question regarding lower KH valve covers. I have 2 different lower valve cover styles that differ in the hex region. On one the hex is 1.25" and is a full hex like any normal bolt head would be. On the other style cover the hex is larger, 1.375" and consists of short flats that do not connect to each other, but instead have a portion of the cover circumference remaining between them. Does anyone know which cover style was used on which years? But more importantly, does anyone know which style was used on a 1956 K?
Has anyone purchased/used the repop K model valve covers and have anything good, bad or indifferent to say about them. Also anyone know which of the 2 aforementioned styles the aftermakert covers are? Thank you.
