Anyone try the Pro Action 50cc cast iron 200cc runner heads. Seems like a good way of making some good compression with flat tops. Any thing special needed done to heads?

We have some on a flat top 355, they do make real good power, ours are the 220 runners i think. the only thing we did was we had to have the pistons cut to clear the valves, other than that no problems whatsoever.
