I considered the cam being trashed but i think its still got plenty of lobe, the push rods just are not strong enough to open the valves it seems. The first push rods i pulled out were bent horribly so im assuming the lifters have just been riding along the cam with no tension on them. I am thinking this is from the old sticky gas since all the exhaust valves are working right and all the intake valves are sticking. I put a socket under the rocker arm and ran the nut down, the valve opened. I really dont want to pull the head off.
