Good parts are not cheap, I have right at $1000 in my Hedman headers including coating and my T&D rockers were almost $1100, push rods, almost $400. Quality parts that make or can withstand a bunch of power are not cheap. No matter what brand is on the hood.
Indy stuff can make excellent power when in the right hands and the correct parts to compliment them. I bought mine used un ported and called Indy just to pick their brains a little. I was on the phone with them for about 15 minutes and never felt like I was being put down or hurried to get off the phone. Having said that I have read the horror stories too so there is some issue there. I've read of many people having issues with Dave Hughes too, but I've had many conversations and never had an issue.
With small blocks getting bigger all the time we need heads that will support them. If you're running a stock stroke 340 with a purple shaft cam the new Edelbrock Victors or Indy heads are not for you.
I have a very good set of Edelbrocks that were on my 408 but when I built the 434 I knew they would be a restriction. I have no regrets using Indy heads on it.
Your mileage may vary.
