With aluminum heads and enough overlap on the cam, you should be alright.

If you are planning on keeping the cam you have you will probably have a problem. The cam you have in your sig file is designed to make high cylinder pressure at low speeds. The limit is probably 10 or 10.25 with pump.
There is probably a .055 thick head gasket that will drop it about .15 point from a .035 but I think you might have to find a cam with a little more duration. If you try to get something with a much tighter LSA (which is really what you need), the closed loop operation will be affected.
