Hey guys, working on my 91 LX. It has stock heads, stock rockers, stock pushrods, and hydraulic roller lifters. I swapped the stock cam for a F303 put in new springs and retainers. After assembling the heads there was some unusual play in the pushrods... probably a couple tenths and least. One of my buds, he is a chevy guy so don't hold that against him, thinks that since everything was drained that the hydraulic lifters need to be pumped back up with oil pressure and that play will get taken up. Not sure and I don't want to have to order new gaskets and take the time to take it apart later and find out that wasn't it. Has anyone else come across this? Any thoughts would be very appreciated. Thank you.
