360 build ????s

I know the Torker II is not the best intake out there. I am using what I have at the moment. The "proper build is not in the books right now. the 318 was in the car and had a flat cam. I want to throw some pep at it and this is the cam I want. I found these heads at a swap meet and missed the shaved portion of them. My bad. All I have into this build is my time and the money for the cam setup, gaskets, and the heads. I only paid $325 for the heads with adjustable crane rocker setup. I chose to not use the rockers so sold them. So the head to me were basically free and I know I can salvage some funds back out of them if I want to. The 360 option I talked about initially was not going to work for me at the time and still doesn't.

I guess a question I can ask is. The heads I took off the 318, can I take the double springs from the J heads and install on these? Or do the larger valves on the J heads and smaller valves on the 318 heads make this not happen?
