But I digress. With flat tops you're not building an LS7, more like an L36 so the stock stuff should work.
He's building a seperate motor to LS-7 specs.

the rockers are for his truck motor.

Just check the inside of the rocker arms, if any of them are galled from lack of oil, those should be replaced. Pushrods, as long as they are straight, are fine, make sure they are not plugged up at all.

Follow correct break-in procedure for the new cam, use the right oil with correct levels of ZDDP
