Indy 360-1 vs TFS VS W2

Yup. They are sure on there alright.

For all out flow, you ain't beatin the W2. You'll have stupid money in um, but they'll haul the mail.
My knowledge is a little light on the extremes of there porting abilities or maximum.

The Indy has two, W2 styles heads with one being an oval port and the other, rectangular. At there sight, they list a few fun facts including there suggested CID for bet results on the heads.

I also don’t know how far these Indy heads can go. Things like cfm flow, cross sectional area, etc....
