I've used Wood cams on two occasions. The first was a set of 400G's in a 106" FXDL. The Bike was a Torque Monster, but the valve train was very noisy. I was able to quiet it down some by using an over-sized pinion gear to take up the lash, but it was never even close to quiet. The second time was just recently with a set of TW6-6R "Conversion" cams in a 95" 2004 FLHRI. Those cams were incredibly noisy! I was running stock springs and went so far as to tighten up the rocker clearances. The only thing that made them any quieter was to adjust the push rods down 4 turns as suggested by Bob. They were still so noisy that I wound up replacing them with a set of Andrews cams and now the bike is quiet. They did make good power, but I couldn't stand the noise. The engine sounded like I had marbles rattling around inside the rocker box's. In fairness though, some people have said they were able to make em run quiet but I never could.
