Closest comparable head is probably the Indy EZ-1 or perhaps the EZ-295 since it is CNC ported. I think the 295 head costs a little more and comes with 0.600 springs and steel retainers. The 270 head comes with 0.700 roller springs and Ti retainers. One of the Indy dealers can correct me if I'm wrong.

I'd say the consensus is that TF build quality is better than Indy build quality but once again engine builders who have experience with both can weigh in on that.
