Recently added cams - Problems???

Work Done- SE 204 cams, SE Adj. pushrods, lifters, bearings, SE tuner and dyno'd
Bike- 2012 Wide glide, Vance Hines 2-2 Big Radius pipes, SE air cleaner, K&N filter.

So after getting my bike back I noticed the engine was alot noisier then before, sounded like a ticking from the cam chest area? But my thoughts were this was normal given the upgrades?
Well, next day I was filling up and checked my oil (amsoil) and had foam/bubbles on the dipstick. I figured no problem Ill ride a couple hours and water will be gone. Well it didnt leave after a 2hr ride so That night I started looking around to see if I could find some info about what causes this and I think thats were I messed up! I have found so many different stories and answers over the past few days I am totally lost on what is wrong, if anything at all. So, knew I could turn here and get this shit straight! Thanks for the help!

The pushrods might be adjusted a bit tight, they're noisier when too tight than too loose !

Who did the work?
Take it to them and ask...
They can easily re-adjust rods if they are too tight.

Leave the gun. Take the cannoli.

Pushrods are likely adjusted too loose. SE adjustable pushrods call for 2.5 turns. They're 20 TPI and work best at 3.25 turns, which is about .0140" in the bore, vs .0100" in the bore.

So.... Dave, you are telling me I should forgo the instructions on the SE quick rods of 2.5 and go for 3.25?

With stock cams you can get away with. 0100 inch depth.

2.5 turns sets the tappets to a .0100 inch depth. The tappets are quieter at .0140-.0150 inches. The total bore depth is .0200 inches. Going to 3.25 turns or so sets the desired depth. You can experiment on your own and start at three turns if you want. Generally at 2.5 turns with larger cams noise will be heard over a stock cam.

Wow, seems the guy has the same deal here, suggestions are all over the pace. I myself find zero and start off with one and a half turns. but then that is just my way. But 3 and a half to start. lets bend the valves right off.
