NOOOOOO! that will make it worse, cuz the ICA would be waay too early, trapping even more pressure. I have the stock cam listed at 240/236/111+1, which yields an ICA of 50* about the same as the Oregon when measured at 254, which I am sure is not correct. And if it was, you would be giving up a lotta power going down 2 cam sizes for no good reason.
