Looking for some suggestions

Thanks. I'm not going to get into the last engine builder I just would like to move forward and get something done correctly. I am in Janesville so I can check those guys out too.

Basically looking for a good street strip motor, something say in the 500hp range. I want to run my Schumacher headers so I'm not sure if those work with aluminum heads or not. Also would like to keep the stock hood so nothing too high. Pump gas for sure.
