Ok so I solved my oil pressure problem. One of my lifters popped out of it's bore and bent my pushrod.
What causes this to happen,and how can I keep this from happening again?
Thanks!

To much cam for the valve springs causing coil bind or the valve spring retainers hitting the valve guide/seal. Over reving the engine are couple of things. Push rod mislocated in rocker on assembly.

You have it backwards..... the pushrod bent then
the lifter came out.... pushrods bend for a few
different reasons.... some were all ready stated

I never had the engine rev over 4500 yet. And then heads are Eddies so I'm sure the springs should be able to handle the 509 cam.
Thanks for the replys!

Did you have the heads checked before install, I've heard of some problems with tight valve guides. That could bend a push rod. Also what valve gear are you running?

No I never had them checked. I'm running the stock stamped rockers and stock valve train.Running the valves that came with the heads.

Maybe double check rockers installed correct, I know small blocks have off sets. Also if the blosk or heads have been milled, push rods could be too long. Just throwing stuff out there. Sorry about your problem, I know this season is is winding down quickly.
