Rocker arm side play

thanks for all the input guys

Dustertogo
The motor is being built it's not in the car
.030 over 360
flat top hyper pistons 9.5-1
comp 480 cam 231@50
stock heads
MoparJ the rockers are not on the motor
I'm real close to putting the motor together so checking all parts now
I think the rollers would be a good investment
any suggestions on who to get the rollers from?
Thanks again Bruce
