This is where a pic will really help or the exact make and model of seat post.
Otherwise if the bolts are on forward and one aft of the clamp, then I'd simply loosen one while snugging the other. Might need to loosen both a quarter turn to get it just loose enough for that to happen.
Or just loosen one a quarter turn then tighten the other, rinse and repeat till you have the angle you want.
Then make certain both are snug when you get it to the position you want.
On some post that have two bolts front and back it works differently. I haven't had one of those types.
Seems more of a maintenance question than a fit question.... just sayin!
