grab the factory service manual, and follow the procedure in there. Not like our valve train is very adjustable........ i think all it is is torquing the rockers down, and that's about it. Don't quote me on that though.

Print this to use. Install all the rocker with adjusters loose. Refer to the chart for the corresponding rocker and tighten the adjuster to zero lash. Zero lash is when the rocker takes up all the slack or up-down movement out of the push rod as you tighten the adjuster. Then tighten down 1/2 turn more and lock it down. Do this to all 16 in order run the motor listen for noise. 1/2 turn is a good starting point may need 3/4 or 1/4 turn.

You can buy rocker arms in any ratio adjustable or non adjustable, stud or pedestal.
There is no adjustment on non adjustable rocker arms, so the op's comment to hey you about 1.7s negating the use of the FSM may or may not have any bearing on the appropriate procedure for torquing down rocker arms. Until he tells us exactly what he is working with, nobody can offer anything except speculation.
