I completely agree on the price problem for W2's. However, if your interested in some serious big power, that is where it is at. The Indy X (and other aftermarket iron) heads are excellent in there own right. The W2's are an aging head. Cheaper and better iron heads have come around with excellent ports to carve. There performance ceilings aren't as high, but, do perform very well. They should be awesome street strip heads.
