The Tigers have more real estate to work with, taller port, less water jacket and pushrod holes in the way. Your experience may vary. Smart people are running very fast with all the available heads. It mostly depends on how much work your willing to put into them.

Good information!
Don't mind us we're just talking non-sense
But on another note, are the Tigers similar in airflow to your RAV heads?
