Stock Rocker Arm Question
After reading a ton of posts I still have a question I cannot find an answer for. Should there be any play/slop with the bearings on a stock rocker arm? Mine have a little side to side movement and up and down movement - normal? I need to change my pushrods, but not sure on the rocker arms.

Up and down....no.
If you have play there...your pushrods are too short.

Off the car they will have play. Of course they will rock up and down without any seat pressure on them.

on the car I had some play and major play where the pushrods were bent which I understand. I really expected them to be pretty tight and not able to move them with my hand. I'm just trying to figure if I need new ones or not. need to order my stuff today

I run the stockers with a very large cam.
They shouldn't have any play up and down when installed. They might have a bit of left and right play in the bearings.
Have you ever noticed if you have needle bearings on your oil drain plug??

I would assume they are fine then.
Hard to see exactly what amount of play you are describing via words.

Sounds good...
But I wouldn't use a factory valvespring. I would go with the PAC version of the Comp 918's.
And maybe a 224/224 cam. Hotcam will get a little power for you, but might as well get a touch more out of it for the same cost and since you will be paying for or doing the install anyways.

Totally agreed, The hotcam is not worth either A. the money for the install or B. The time invested for the install. You will regret going hotcam more than likely. A 224 is 100 % DDable. Do as mentioned above, your spending the money anyways, might as well make it worth it.
