Cyclinder Heads/What Type
 

I have 2000 35 Fountain Lightning with carborated 500 hp's with tall gill exhaust. I was told it has a 600 lift cam, stock? Should I use Dart Iron Eagle Cyclinder Heads with 308cc intake runners? Any suggestions?

Thanks!

This is more a general tech question than a beer budget/DIY one. Posting there will get you more responses.

Making a head suggestion requires a bit more background on what you want to accomplish and your budget. You can do alot to the 500HP. I believe the stock cam is very similar to the Crane 741. The Iron Eagle is a good moderate performance head. You'll see an increase but not a ton. A set of AFR 315CNC's will give you quite a bit more gain but they'll cost you about $1500 more a set.
