SE259E excessive noise
I've had cams, all my buddies have had cams of all sorts and makers. It makes no sense to me why HD would install something that beats up the valve train. I got an answer: the SE259E (and all of their cams) are a old cam design never $$ improved, it literally throws the valve open and slams it closed creating the noise.
Modern cams makers have resolved this problem to a mild noise level and it only makes sense the wear and tear at idle would be less and of course through the RPMs.
Anyone care to expand on this I'd sure like to hear from the Big Dogs.

SE cams are not noted for fast and noisy ramps. I know a couple of guys that are running SE Stage IV kits with the 259E cams and they are not noisy. Reveal more about your setup; probably another reason for the noisy valve train other than the cam set. What pushrods and lifter are you running? Have heads been decked? What head gasket was installed?

Another negative attribute of heavy springs is the added noise of the valves hitting the seats harder. Stock beehives may not be able to control valves at high rpm ranges but are much quieter than the heavier SE springs. Stock beehives will work for most applications as these motors, even built, don't see high rpms unless built for the track and who cares about noise at the track?

The cnc heads in the later stg 4 kit uses an ovate beehive. I have no knowledge on whether the springs used will hit the stock lower rocker boxes. I do know that the springs used on the mva's hit my stock lower rocker boxes and made a terrible racket. I didn't know about the SE pre ground lower rocker boxes at that time so my stockers got ground for clearance. I'm still using the monster 520lb SE dual springs, valve train is not making "loud noises" anymore. But what is loud to some is not bad to others.

SE CNC ported heads SE 58mm TB
10.5 SE pistons SE clutch spring
SE259E cams
SE pushrods
Just the bolt in kit (no machine work). To me it sounds like the push rods are not adjusted correctly.

I am going to take it to an interdependent shop and get thier hands on NON HD assessment.

What's to adjust? The kit doesn't come with adjustables. It isn't the cam profile. Most likely it is an install issue or possibly bad lifter(s)
