I will be installing these soon and want to do this correctly the first time.

I will be using comp reusable rocker bolts,

zzp 6.95"-5/16" pushrods (i just bought 7.05" stock length, but zzp says that will be too much preload for LS7 lifters.

i have cometic .052" head gaskets, which is .010" thinner

heads are milled .005"

stock rockers

stock valves

nic cam


do i set lifters on base circles or does it matter if they are open or closed with these engines? Then after that, what about preload. what torque + * of turn

Thanks in advance
