OK, I've been reading the different threads about installing an 02+ LS6 cam in my 5.3 and the difference in the base circle diameter. I need pushrods that are 7.40" right? I found a set of stock LS1 pushrods that are 7.4. Are there any problems I may come across? I'm not planning on reving the engine crazy (probably no more than 6000 rpm). Also, I'm looking for a set of LS6 springs at a good price. Thanks.
