Im making a solid oak single bed
3 x 3 oak leag 15" high capped with walnut tops to hide the end grain
61/2" side 3/4" thick the clip fitting to hold the sides on
do you think its ok to just biscuit the joints on the bottom and headboard
ends?

Do you mean side rails to bed posts or headboard to bedposts?

I'll assume you meant the latter. In building my last bed, I used a mortise
and large tenon. Beds get a surprising amount of unusual forces for many
directions.
The rails are attached using two of the the large Rockler rail catches on
each end. (See other post for link)
