A-65 and C-85 valve cover screws

[ralf]

Found some cast aluminum valve covers for the 65 HP and the 85 HP Continentals. Due to the thicker flange, I need longer screws. What type/size screws are these and what is a good source? I don't know anything about aircraft hardware and when I looked at an aircraft hardware catalog there were multiple types. The existing screws are what I would describe as slotted, pan head machine screws.
