Well after all those questions on the heads, I am near the last question that coincides with heads. Valve covers, now that I am running roller rockers I am afraid on Wednesday when I think my car is going to work that my valve covers wont fit. I have stock VC's, Twisted ALuminum heads, and Tubular GT-40 intake. Do I have to buy new VC's, that will throw me off even more days and money. I was told that the stocks can be modified. I would appreciate the input, ohh and if I have to get new one's is 3 1/2 big enough or 3 11/16 or are all of those to big to clear my intake, I am looking at some on E-bay. Thanks.
