Which Roller Lifters to Use? I'm getting ready to purchase a set of new roller lifters for my 306, and I would like to know if its worth it to get a set of Comp Cams roller lifters or should I just get a new set of Ford Racing stock replacement lifters. I can't find any info on the Comp ones to tell me if they are lighter or stronger, or why I should go with them. If it helps, I am using Trick Flow Track Heat heads, and a TFS stage one cam. Thanks for any suggestions!
