Adjusting valves

I was wondering if someone could tell me the correct procedure for adjusting the valves on a 1989 302 with a Roller Cam?

Still should be no adjustment required. Did this motor have a roller cam to start with?

Ok, I read through AllData and Mitchell.
There is a Valve clearance check (similar to the old Chevy way)
However there is n o adjustment, if your clearance is out (.125" - .175") then you can get .060" over/under sized push rods.

So you just need to Torque the Rocker Arm Fulcrum bolt to 18 to 25 LBS FT
