My Tiger head design still has allot left un discovered, and guy's like Calvin are just starting to bring it out. This head was designed with allot of room for diversity and I'm glad to see that some are tapping it. I have a prototype from way back in 2003 that I used for R&D that has several different port configurations. Some of you might remember seeing it at Norwalk or in the article HPP wrote when I first started showing it to the public. One port is the as cast that was tested for the article that flowed 422. Another port is a max effort port that flows 480 cfm with a 2.350 valve. Another is a port very similar to what Calvin has done (not as wide) that flows 440 with a 2.250 intake valve.
Nice work Calvin, glad to see you playing with some Tiger's.
Happy Holiday's to everyone!!!!
