Hey Marty...
I do remember seeing that post..but some guys in here taught me the touch and feel exhaust port method...basically take off yer exhaust manifold...feel inside and adjust yer valves till they are flush with the inside wall..works perfect...gunna double check this year to see if they offset...but I liked that technique...
If I find the other thread I'll post it for ya...

Y.P.V. adjust
Here is two ways of gett'n her donnnnne!!!!
Allen key method;

Feel method;
This is step one; let it warm up abit and remove your servo cover & just screw out your idle (rpm) below 1000-900 rpm and watch the servo rotate, kill the engine and mark the spot with a black felt pen…and mark the open and closed positions…now double check by readjusting the idle to 1700+/- 100 rpms and start and stop the engine and watch the servo and see if it opens to the mark you made…if so than there is no need to do this step anymore…I just use a pair of adjustable pliers and rotate the servo to the mark…Step two; remove the centre pipe, remove the exhaust manifold…(yes it is a pain)…now that the exhaust is off, you reach inside the exhaust port and feel the valve…it should be flush to the port-check all valves…now rotate the servo closed position and feel the valves close, if one is hung up than the(y) should be taken out and cleaned…if they all close o.k. then rotate your servo open again and reconfirm that they are opened…if not than adjust each valve at the servo…your are adjusting then to full open…keep an I eye on the servo mark as sometimes when you are adjusting them the servo starts to close abit…after adjusting, confirming that they are flush with the top of the port than your ready to close the exhaust up…Step three; replace the manifold, the centre pipe and the servo cover…FIRE HER UP…that sweet sound is back…your done…
Hope this helps out...good luck
Note: You do not have to adjust your valves every time you clean them…if your careful when removing them & they are not gummed up to the point where you have to take pliers to pull them out or if you have to clean the valve housing assembly…then you have to adjust everything up again…
Good Luck...
