You don't fix valve float by replacing the lifters unless you put lighter ones in there and reduce the mass acting on the weaker valve spring. And you don't need anti pump ups if you have a stable valve train.
Have a nice Xmas too.
I am planning on checking spring pressure first, and replacing if they're not up to spec. Just a thought while I'm in there is there any benefit to also swapping lifters.
the original question, "Does anyone have any experience switch from the Hi-Energys to Pro mag lifters?"
