[Alexisobs95]

So recently I replaced my cam for a bigger one including springs problem is all my pushrods vented what could be the issue here intake lift is 480 and exhaust lift is 480 do I need shorter pushrods hopefully someone answers my problem thanks

What is vented? Did you mean bented? If you meant bented you far bigger issues such as retainer to guide contact or piston to valve contact which is less likely. Guild to retainer contact at the minimum usually trashes the valve seals , but can destroy lifters and the cam.

Yes I meant bended sorry I just asked my local performance shop for something not that big he gave me this option of cam that I only needed to upgrade the springs but now it seem I need more stuff upgraded my question is I don’t know if you can answer is do I need bigger pushrods or what seem to be the problem?

So what's to blame here? Did the springs fold the pushrods or what?

You mean watching valve opening and adjusting it ?

If you did it with the engine running how far did you crank them down? Or did you set it with the engine off?
