Roller much better. Call a cam company and tell them exactly what you have. If it’s street they can build you a lobe that’s easy on parts. By the time you buy roller rocker you’ll have around 2000.00 dollars in it. Give or take.
That’s alittle more then I was expecting to spend to be honest I knew the rockers would cost me about 600 from what I’ve seen online didn’t know the cams, lifters and other parts would be that much
