hopefully someone on here can help me out. I will be doing a cam swap on my ls1 tomorrow. It is a 2000 ls1 motor. I am installing an MS4 cam as well as new lifters and an oil pump. Can someone please fill me in on what all gaskets I will need so that I can go ahead and order them. Also, should I get an LS2 timing chain and the trunion upgrade? The bottom end is completely stock. Being that the cam is so large, should I worry about the PTV clearance? I hear of so many people just putting her in but is a degree wheel a must? Any help would be great. Thanks
