New to site with 360 question

Johnny, the MoPar fan!!!!!!! Welcome aboard.

I will assume the 380/360 create engine is stock. From here, do realize that basicly, this create engine is a stock production engine with an intake, replacement pistons and a performance cam with valve springs to match it. That's it.

Now you know this is a basic, and very at that modest upgrade with lots of room to work with what you have. The very first place I would look to improve what you have in the horse power area is some head work. It is a very good testament to these heads in stock for that they allow the engine to make over 400 HP as they are. Cast stone stock.

What tube size headers and exhaust pipe are on the ride now?
How many accer.'s are on the engine? (Ex; A/C, P/S etc...)
Any mods to the OE create?

The Brodix heads are a bit more head than what would (More than likely) be OK for the engine as it sits now.
