Yes you can run your stock heads and cams. At 10.5 to 1 compression, you will need to run 93 octane and have it tuned though. Expect a nice torque gain even with the stock heads and cams with the added compression. Scord is on the money. You will really benefit from a cam change and long tubes with that motor. I see 400rwhp NA!
