Pushrod Problems?

Yes a 170 head can be used on a 225. Question, did your push rods come out of that engine?
Yes same push rods different rockers.
We got the rockers from Rocker Arms Unlimited, they look the same as the original.
This was a running engine when we started..The adjusters on the original were adjusted about the same as far as no lock nuts and the adjuster deep in the rocker.
Like I said it was running,but if its a deal where we need different pushrods now is the time.
I'm just not sure they are the problem.
Thanks
