flat tappet, I've heard to ALWAYS use new lifters--the lifters and the cam lobes seat to each other, and bad things could happen even if you mate a used cam to it's broken in lifters IF YOU DON'T KEEP THE LIFTER WITH THE SAME LOBE IT WAS BROKE IN ON

for the small cost, get new lifters...should be what, less than $50?
