I'd see if I could delete or upgrade the cam, lifters and pushrods. The 333's are still small port so I'd look at BWRs or Eddies. There are also some iron big port heads for sale on this site, depending on the price and condition that could also be an option. I have also had better experience with Scat than Eagle as far as finish machining on the cranks. So I guess you could piece together a better "kit" for not much more money.
