Am I allowed to go with my instincts or will you insist I call?

Obviously don't fold for one if the turn is a 9 or 10. Otherwise, trust your read. Your description of the action is a bit confusing, but I think you're okay to fold here. The best you could hope is very aggressively played A8/99/TT/87 (the latter you'd have odds to draw out on). But realistically, you are beat too often compared to the effective odds for a calldown.
