pushrods don't generally "just bend"... something has to precipitate the issue. without figuring that out, you're just gonna bend two more push rods.
so the way that i'm reading it, is you took the head to the machine shop and said: yo, check this out. and then they called you after [insert amount of time] and said: hey it's ready, come bring us money.
so then you meandered on down to the shop, gave them a stack of folding money and went on your way without any discussion of the work that took place in exchange to said aforementioned folding monies?
