round two low idel

I dont know what the popping noise is..
compression test yes with the last cam was like 140-145 was very low with that cam which is why I changed it.
Umm about the springs I dont think its leaking in but I do know that I have 40 degrees of timing at 1500-1800 when I checked it...

I had water in my oil, but not a whole lot, I had to check the dipstick like 3-4 times just to get some on it when I checked it the first time. I changed that oil out...I believe this was all happening because I didnt put the intake on correct.. I hope to get rid of this annoying pop first then worry bout the idle later
