Purney,

Great news. I think you can loosen the rocker arm adjusters all the way and slide the pushrod out. If they aren't too gunked up, the rockers can slide sideways on the shaft for a little extra working room.

You will have to get two new pushrods...I don't think you want to straighten them. The most important thing will be to see if the valves are free to move and not frozen shut with varnish. This could be why the pushrods bent.
