MS4 would be a good cam, but if you dont want one that big a TSP 224/224 or a TSP 228/228. it all depends on what kind of power you are wanting and what your future plans are for the car.

Hot cam or ASA hot cam will work best with those rockers. Anything more aggressive is gonna need some dual springs. Id sell the rockers and use the money to buy a proven high lift cam like a tr224 or TSP225. They will work with your current 918 springs.

Any high lift cam might run into problems with the 1.85 rockers on a stock bottom end. Maybe go back to stock ratio rockers, or find something with a little lower lift to clear the stock pistons. You figure a cam with about .580 lift(rated lift with 1.7's) will be about .630 with the 1.85's Vs 1.7's. I thought you start to run into problems in the .610-.620 range. If you get something in the .560 area you should be fine, that would put you at about .610.

As said before....go with the Hotcam or GMPP ASA cam. If you want a nice performing cam that will be reliable and very streetable and sound pretty nice, go with the Hotcam. If you something that's a bit wilder, with a rougher idle, and a NASTY torque curve, but still pretty street-friendly, go with the ASA cam. Those are the best with those rockers.
