So I put a set of 9.59" long one in it which are the right length . When I had my heads serviced .015" was removed from the valves and the seats and im not sure if the valve stems were trimed doown to compensate what was taken away from the valves and seats. So if thats the case I will have to get a set of 9.56" long pushrods to make everything work together. My intake makes power from 2500-6500 RPM and im runing a stock cam.
I would have to pull a book and read, which I do not have the time or energy at this moment, but there is a tool that can be used to find out exactly what length pushrod you need.
