I'm installing an LS3 stock cam on my 5.3 and I have the LS2 timing cover with the cam sensor and the LS3 timing chain with single bolt cam gear and crank gear I know I need to extend the cam sensor harness to reach the front. I'm also installing the LS6 valve springs. I was wondering if there was anything else I would need and what gaskets I need to replace or are they reusable? Thanks
