It's pretty funny to see the negative report from Hughes on these heads.

On my 2000, I broke a valve spring so instead of spending $500 on stock heads (valve job, resurface, new valve, new springs, seals, etc), I opted for the new Indy heads.

I got the 2.02 version. I didn't notice much difference but the top end does pull harder. However, my motor has the stock cam, exh manifolds, so it is begging for a cam! Basically, when it comes rebuild time, I will have all the head I need.
