Ok guys, here's an update on my situation. I located somebody selling a roller conversion kit, with all the guide plates, lifters, timing chain,cam gear and hardware that I need. He also is selling a timing chain cover and harmonic balancer(from a late model 5.0) My question is, do I need the timing chain cover from a late model 5.0 since I am going to be running a roller setup, or can I use my factory cover off of my 68's block? And assuming this is a 50 oz balancer should I jump on it if it's a good price? I also located a set of headers that appear that they might work off of ebay. If anybody could please take a look at them and let me know if these would work in my situation i would greatly appreciate it. Here is the link below for the headers:
