i installed mine last month. I let it rev at 3k for about 10 minutes after install. Just to be safe since other brands recommend it. I just lubed up all the cam lobs with oil after i finished
FYI. zip tie the cam gear to the chain so you don't skip teeth

Did you use assembly lube
Did you only replace the cams and kept all the original springs rockers etc
Did you add rocker stoppers
Did you service your lifters
We?re your cams a dull finish like mine
Did you get retune

Sorry so many questions

No I didn't use assembly lube. I just oiled everything up.
I replaced only the cams. No RAS. No service. Yes they were dull like yours
Yes I got a retune. Now it has a nice lumpy idle

My gains are not exact since I have a boost leak on the second dyno. I gained 10hp and 30tq

Hi all, I put the cams in over the weekend and everything went well, did the break in 20min Erving between 2-3000 rpm followed by a long freeway cruise at about the same rpm and all is good .

I do have a question thought .

Today I went out for a cruise and gave it a couple of light squirts , nothing major just mild hitting boost here and there. I did notice there is a more than usual blow by smell as I do vent my rocker cover to a vent to atmosphere catch can. Is this normal?

I was thinking and is it possibly because when I installed rocker stoppers I removed that plate (pictured below) that I assume covers the rocker cover vent from capturing oil off the cams in the area directly below ?

The funny thing about blowby, is all your rings are cruddy and your seals are clubbed and your heads full of horrible sludge and carbon chunks.

And, it's funny.

Maybe you should put a catch can on your catch can, so you can catch the blowby caused by the catch can, and vent it into a fifth catch can.
