why else do you think the pushrods would be bent? Did you have the engine decked, or the heads milled?

It's been a while since my last post. It turned out that the bent pushrods, were caused by the cam making more lift at the valves, than it should. The valve spring retainers were hitting the valve guides, so obviously something had to give. In this case, the weakest link was the pushrods. My cylinder heads are currently at the machine shop, to have the valve guides milled, and the valve seats cut a bit more to improve rocker geometry. Hopefully, I'll get the heads back by the end of this week. I'll be back, when the engine is back together!
