I know that as I rang ford myself. they couldnt however tell me anything about the pistons. im happy to be proven wrong on it.on another note, it suprises me that rdp would remove the engine from their fg to do valve springs, head studs and oil pump gears but not replace the rods while it was out. doesnt make sense. I guess they want to find the limit of them and can obviously afford to do so. Link to comment Share on other sites More sharing options...

As I think they just used the smaller head studs that keep the stock holes in the block. Could be wrong though Link to comment Share on other sites More sharing options...
