car already had 1.8's on it, so i used a smaller lobe lift combined with larger ratio to achieve the net lift i wanted. .3241X1.8=583.

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?

Nothing wrong with them. They just won't allow you to run LSK lobes, that's why I asked. You'd need the Patriot Extreme springs to run the LSK lobes.

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

228/228 would work well with those heads. Lift is HP, which is why Patrick is asking about your springs. Check Pat's sig to see how much you can do with a cam < 230*

Seems most have have decent spring life so far as long as they are setup properly.

I made 390rwhp cam only with a TR 230/224. So you should be well over that with 243's and a decent cam.

Silverbandit: without knowing what cam you're using, how did you know what size combustion chambers you need?

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.
