You could have gotten over 400 rwhp cam-only. Breaking 400 rwhp with PP 243 heads milled to 61cc and a .040" gasket can almost be accomplished with the stock cam. Now you need to ask yourself the question, how much over 400 rwhp do I want? There's no free lunch as the additional overlap will take a potential toll on street manners, but you won't need lots duration to get there. What is the max lift that you are willing to run? Using anything better than PP Golds for springs?

Which are pretty much the same price.
It is a stronger spring, but is just as available, and as said similar in price.

IMO go with something like a PRC street or Patriot's higher end head, that with the 224/228 580s will make your car scream, and be totally drivable.
