Thanks B3RE, as I said I was skeptical about using the Indy pieces to begin with , I don't think it was caused by a geometry problem as my then engine builder took great pain in making sure the geometry was correct. Its worth noting that on my W2 heads with the old ductile iron non roller style rockers I have never had a problem after a few thousand runs and over 25 years only replacing an adjuster bolt once. I just think it was a design problem in the rocker itself as a friend that ran the same set up had the same problem. I have already spoken to Hughes and sent them an Indy rocker and they say their rocker is the same size which would be good as I don't really want to change push rods. Fixing the 408 ( cracked crank and rocker problem ) is on hold for now as I am running my 367 for now until I decide what to do , I have considered selling the whole set up as the R3 block alone is worth quite a bit of cash but I have been advised not to sell so when the funds become available I will fix it
