If you have removed your bonet lining then there will be a small gap between the top of the heatshield and your bonnet. Ive removed my lining too but left a small square just over were the heatshield sits, about 30cm x 30cm just to seal against the heatshield when bonnet is shut.It wouldnt be much of a gap though if i had removed it all, about 1.5cm i reckon at most.
