Depends on the cam. You should always measure the piston to valve clearance though since every engine is slightly different.
If you're on a budget, Trick Flow has an entire heads, cam and intake package that is reasonably priced and is designed to work well together. It also comes with all the little things you need like gaskets and bolts.
