what wrong with indy's
Nothing in the intended application, In a 540 Cubic inch NOS motor IMO is not one of them. I bet the engine has a solid roller cam and 600-700+ lbs open pressure.
I betting the guys at Indy's own personal engine's doesnt have them in this type application for good reason. 
I would use them in a second in a mech flat cam street car. 
If there is money well spent in any performance engine it always pay to have good valve train equipment.
I would use stock stamped rocker arms in a street engine, even if I was given a NEW SET of ProForm rocker arms...WHY? I know the stock stuff can take the abuse for 100,000+ miles of use.
