Indy rocker I broke a few years ago on my Indy headed R3 block 408 : 600 lift cam shifting at 6500 not a lot of spring pressure . Indy no longer offers the rockers I ended up buying a used set from a racer in Md an 8 hour round trip to get them. I damaged a few more after the repair but luckily had spares , I sold the motor after the crank cracked. I have since gone back to my ancient W2 heads on a 410 c.i. 360 block stroker with the old ductile iron non roller rockers I have ran for over 25 years without breakage or a problem
