So I recently bought a slayer pro and have already spent more money than fiance thinks is reasonable. So naturally I want to spend more. My question is about the rocker arms. I want to get the progressive 3 rocker arms. I read in some other threads that you need the push rod spacers but the website says I need to use part #5319 push rods. Research tells me these are for the revo. So do I go with the spacers and stock push rods or the revo push rods? Thanks for the help!
