535 supercharged first start up... Didn't go so well. thoughts needed?

Here is a better picture. So what do you think caused that. The rocker arms don't have a scratch on them.

That wasn't 'caused' by anything in your engine, that was ground on by whoever disassembled your heads so the valve would come out through the guide. They mushroom sometimes and won't come out through the guide, so I usually use a file to straighten the sides of the valve stem tip, but someone was in a hurry and used a dremmel it looks like.
You really should take more time inspecting your stuff before you pay the man and especially while assembling. Not trying to bust your balls, just saying.

Thanks. It is a 535 mild cam the cam guy said that I need a 125 P

Yeah, I should have checked into a little more

This year I'm dealing with now is the cam guy sent my new roller cam and lifters and a inner spring that I was supposed to just to be able to install to make it 125psi. If you've looked at the pictures you will see that with that current setup the heads would have to come off and have machine work done and a different style of valve seal would need to be used. So now I'm in search of a single spring that is a 125 psi with a install height of an inch and 7/8 I'm doing this on the car not wanting to pull the heads

The valves that were installed in the heads were new stainless valves That's why they were at the machine shop

Someone ground on that, plain and simple. Nothing in your valvetrain could cause that. Sorry. Wasn't trying to offend.

Didn't even think that. And thank you. I didn't think it was anything valve trained did

Does everyone agree that my setup didn't put a bevel on a couple valve stems?

Those valves would have to be awful soft to wear like that on just a start up IMO. I saw the reply "I didn't pay much attention" often throughout this thread, I think that alone contributed. I'm not trying to be an *** by any means but that's something you have to do. As mentioned by Hawkeye, that lifter likely wasn't spinning causing the damage. And like dvw said, those valves were likely already like that or at least suspect.. those are things you have to inspect as the motor goes together along with clearances, cleanliness, contact patterns, etc, etc.

I've yet to loose a cam on warm up, maybe I'm lucky, maybe it's something I do??

This is my new roller cam .. now I'm just trying to find a set of springs that will have the right pressure to replace the ones I have. The factory style diameter and able to use the factory style valve stem seals. I believe with only a 500 lift that 125 or 130 PSI spring will work. Anyone have any part numbers or any thoughts would be appreciated

You’re kinda of putting the cart before the horse.
I don’t think it’s wise to use a roller cam and then compromise on the valve springs to fit a stock head and rocker arm.
If you don’t want want to machine the heads for dual springs, and use adjustable rockers, you’re better off choosing a hydraulic ft cam and single springs.

What I am wanting to do is find a single spring that will accommodate a .500 lift roller cam and lifters with at least a 125-135 psi seat pressure and measure for the push rods and add .015 for preload and run the factory rocker assy...

You need the correct springs, locks, retainers. and pushrods. Call the cam company and get their recommended spring specs. Then check spring pressures. Just adding a inner spring to an existing spring is a poor idea. Inner and outer springs are designed to work as a unit. Retainers for dual springs are stepped. Get the correct retainer for the spring. You need to measure installed height as well. Stamped locks are suspect. Get machined locks. With a hydraulic roller the pushrods will need to be shorter. Yes this will drive up the cost. But not as much as when the valve falls into the cylinder when it bounces. Take a look at my buddies Hemi from last weekend.

 

[63dodge440]

Thanks, iam working with them to get the correct parts

 

[HEMI-ITIS]

Is it just me or do the springs look too big for the valve spring retainers?

Looks like lash caps are laying on the retainer......

Are you sure? Did you change retainers when going with an inner spring? How can adding a inner spring to a single spring be correct? Silver locks are stamped, not machined.

I believe with only a 500 lift that 125 or 130 PSI spring will work.
What is this figure based on?

[63dodge440]

I am not going with an inner spring. The inner spring was sent with the new cam and lifters to make the spring pressure 125 PSI. But since I am not taking the heads off in order to run the roller cam and lifters, I need a seat pressure of 125 to 135 with a single spring.

 

[63dodge440]

I believe I found the right springs with the right seat. Pressure was towed by the machine shop. They should work fine. He suggested I went 30 to 35 thousands preload when I measure for the push rods. And not 15 thousands. He said not that it wouldn't work but you may get some ticking from the valve train

 

[RemCharger]

. They're stainless steel Chevy 202 valves. He said sometimes exhaust valves are like that

Chevy 202s are intake valves.
And they won't seal well in a 2 08 chrysler seat.
As mentioned several times... stamped steel rockers are marginal on FT cams... not many people would try them on a roller.
That can certainly lead to extreme valvetrain noise. Ie; punched rockers

The heads have been machined to accept the Chevy valves... I guess we'll see what happens. May just be a paperweight lol

You have stock retainers? Stamped locks. Chevy valves. Are they 3/8" stem, 11/32" stem? Are they the same installed height as the factory valves. Now you are are looking for a 125#-130# spring. Where did this number come from? What installed height? What diameter? What open pressure?

He will probably throw this junk together and go out and run 9’s
