Indy Head/Bad Rap

If you're looking for a great head package in the RPMs, get them from Jeff at Modern. I've seen his std port RPMs make past 600hp on pump gas 4.15 stroke big blocks with medium sozed flat tappet cams. Hand porting is much more $$. Indy CAN do good work. The issue is they tend to feel they can rush and it still qualifies. I had a 438"/500hp wedge they sold for $9500. It was nothing special, hydraulic cam, SR/EZs. It never made more than 450hp (except on thier dyno where they ran the A/F at 15.2:1 to make 508hp. No dyno could repeat that) It leaks, it pings, it's a mess. For $9500.
