Roger, definitely a type-O on my part, "Now" shoulda been "NO"
The way this site used to operate, I coulda went back and fixed that, If it can be done now, I have not figured it out yet! The only way I know of now, is to contact one of the big guys, and have them do it.
Regardless, I still would have had to catch it 1st. Sorry.
Even in changing the length of push-rods, Either:
1) You usually select a longer rod that will position the inner part of the tappets, into a different location and the tappets still work as they should.
2) You take out all of the tappets adjustment, with the longest push-rod possible (rendering the tappet into operating as a solid lifter) The Bad thing with doing this is, each push-rod must be selected to perfection, as not to "keep valves open" and to allow for expansion. Older vehicles (like way on back!) Had solid lifters and a "screw type" adjustment, feeler gauges were used to provide correct clearances.
Still, amongst all of our bickering, we have not heard from you?
Is is this "Pinging" (detonation), or is this Valve train, Rattle and Clatter?
As Wenchtech said, "Check the Timing, EGR, and a fuel upgrade may help (Either situation) Along with a full scale "Tune-Up" and maybe the Marvel Mystery Oil. Then on your next oil change after that, use a "oil stabilizer" in with your oil, follow the bottle's directions.
