Bent up stuff

So far I have not pulled the heads to look. I did fill the cylinders up with air using my compression gauge. No air escaping was heard. All but three pushrods are bent which makes no sense. However, I also discovered that some of the roller rockers are contacting the springs. So, is this what caused the bent pushrods? Or Maybe the fact he went with 7.250 pushrods which are a lot longer than my previous ones. Basically, 7.250 pushrods, 1.6 rockers and a .570" cam. Why would longer pushrods be needed? My stock ones were shorter with a 509" cam. This is why I am looking at the pushrods as the culprit currently. The solid lifters literally may have bent the **** out of them. I am going to get an adjustable pushrod and do my own checking.

Correct pushrod length will allow the roller to be as centered as possible above the valve stem. If your pushrod length is either too short or too tall it will position the roller off center and will cause an uneven sideways load on the valve.
