Why on earth would anyone use these heads? How could a major head manufacture build a head with so many dimensions incorrect? Whoever signed off on these heads should be unemployed. Power wise I've yet to see one much better than an -1. Nothing fits. You have to ask yourself why? I've seen plenty of complaints about Indy as a company, but the castings are used by the thousands without failure. In fact I think I've seen more failures on the few Victors that are being run. Nice work on the fix. I just can't see going to all that trouble for little or no gain in performance.
