Bottom ends ARE NOT the same.

Pistons and rods are both different. GT block has higher compression...GTP block has lower compression...I don't think your understanding that switching the heads does nothing for compression ratio. Switching the heads allows for the injector embosses to be in the heads and not in the lower intake manifold like on your N/A car...
