Which pushrods???

I'm going to be installing GT-40Y heads, a crane 2031 cam, crane 1.7 pedestal cobra rockers, new timing chain, lifters, etc. I need to figure out which length pushrods I need. FMS sells hardened rods, which I assume are the same length as stock. Will these work? Some other ones are the TFS rods, which summit sells for $85. Anyone know which length I need? Will stock length be fine?

FMS tech should be able to tell you what length pushrods you need for GT-40Y heads. Since I'm not familiar with these heads at all I can't tell you.
