hey, hows it going. i have a lifter ticking on my mustang at start ups. the ticking is coming from the passenger side of the car. i had all 16 lifters replaced when i rebuilt my engine 3 years ago. should i replace all 16 lifters or is it all right to just replace all 8 lifters on the passenger side of the engine. i will probally buy ford racing lifters, but i do not know what kind of lifters the engine rebuilder put in my engine. thanks
