Ive done it on a stock motor but never before with aftermarket stuff. They are Trickflow Twisted Wedge heads which are stud mount I guess? How do I put them on, what do I torque them to... do I need to lube anything up.... Let me know.

hey try this, with the rockers in place, spin the push rod in your fingers. as you spin it, slowly tighten down the rocker nut. as soon as it gets tight to where you can no longer spin the pushrod with your fingers, tighten the rocker nut 3/4-1 turn more and then lock it in place. the valve you adjust must be closed. if the cam is trying to lift, it wont adjust right

Don't forget that you need your lifters primed when you set the rockers. (If you swapped the cam, this may be an issue, but if you are only doing the heads, you should be fine)

I just dipped my lifters in oil with some assembly lube on the rollers and top where the pushrods go in at.

I used this set of instructions for my valve adjustment:

1. Remove the valve covers, and pick a cylinder you are going to set the pre-load on. Only do one cylinder at a time.

2. Rotate the engine in its normal direction of rotation (clockwise) and watch the exhaust valve on that particular cylinder. When the exhaust valve begins to open, stop and adjust that cylinder's intake rocker arm.

3. To adjust, back off the intake rocker arm adjusting nut and remove any tension from the push rod. Wait a minute or two for that hydraulic lifter to return to a neutral position. The spring inside the lifter will move the push rod seat up against the retaining lock, if you give it time to do so.

4. Twist the intake push rod with your fingers while tightening down the rocker arm. When you feel a slight resistance to the turning of the push rod, you are at "Zero Lash". Turn the adjusting nut down one half to three-quarters of a turn from that point for street applications. Use 1/8 to 1/4 turn for race applications. Lock the adjuster into position. The intake is now adjusted properly.

5. Continue to turn the engine, watching that same intake valve/rocker you just set. It will go to full open and then begin to close. When it is almost closed, stop and adjust the exhaust rocker arm on that particular cylinder. Loosen the exhaust rocker arm and follow the same procedure described before in steps 3 and 4 to adjust this rocker arm.

6. Both valves on this cylinder are now adjusted, and you can move on to your next cylinder and follow the same procedure again.

There may be some initial valvetrain noise when the engine is first fired up but once oil pressure has stabilized and the engine heats up, it should quiet right down to a normal level.

Remember that some racier camshafts will have a mechanical sound to them and will not be a silent as factory units.
