Gary,
 
I used Stainless Steel 2700 Phillips Head Camlocs. However,  if yo= u=20 choose them consider
 
1.  My fiberglass cowl was flimsy so I added a 1.5 inch wide=20 1-BID of fiberglass around the inside edges of the cowl.  Later, in som= e=20 high stress areas I added another BID of carbon.  If you cowl is of car= bon=20 fiber, I still would add 1 BID of carbon to strengthen the edges carrying th= e=20 Camlocs or imbed dimpled washers (Tinnerman's?) in the exterior surface.
 
2. I spaced my Camlocs closer than was recommended, thus avoiding bulge= s=20 between the Camlocs caused by escaping hot air.
 
3. Camlocs are spring loaded - thus, in high speed flight, my cowl shif= ts=20 upward a bit.  I still get bug spatters on the top forward vertica= l=20 cowl face - right behind the prop spinner.
 
4. If I had to do it over again I would use hinge pins (pullable from t= he=20 cockpit) on the straight sides and screws on the bottom cowl/fuselage joint,= all=20 for cowl for rigidity - Camlocs on the top for easy access.  And=20 certainly Phillips Heads to eliminate the "slipped screwdriver"=20 scratches. 
 
5.  Hmmmmm... maybe a cooling plenum.......=20
