correct valve springs

i know the iformations on here somewhere, just cant find exactly what im looking for.

what would be the best springs to run on cr -w- 4000k rpm, 66 and apx 30-35 lpm injectors, scheid street cam. i dont wanna go too heavy cause i think that would be too hard on the valve seats for a dd truck. also, would ceramic coating the exhaust valve face dissipate the heat to protect the seats better?

thanks for the help guys

Springs

Well don't make the mistake/s I have with springs. Don't buy a single spring,.. buy doubles like hp gassers. I had two of the most popular springs on this site and they don't hold their seat pressures and they end up all over the place on their pressures. If you don't have them tested then you DON't know!! I did! After 20k miles they were fatigued and are junk.

I went with Bill Fletcher's dual springs.

Have you checked the dual springs after 20K yet?

The Hamilton springs 110# were updated recently, not sure if you guys are aware. The old 110# are no longer available. The new springs are still 110#, but a better design along with a higher price tag.

Unfounded??

Which springs, how much load loss, what was the difference between spring pressures in the set at x height? I think without answers to these questions, opinions are just that unfounded opinions.

Duals have advantages and dis-advantages. I think blindly calling them a fix all is very short sighted. For one thing they add a great deal of additional mass to the valvetrain. Another thing to look at is the material, treatments and coating.

We looked at pros and cons of different designs with some of the best engineers in the world for springs before we settled on our designs. For the low rpm, lift and mass of the cummins valvetrain a single is more than ample.


Chris Lang, there are many different designs that will work well for you. How much lift does your cam have? As far as valve seats, spring pressure does not affect their life span. How hard the valve hits or closes on the seat is determined by the closing ramp on your cam multiplied by rpm. On the ceramic coating, I have not had the best of luck with ceramic coating staing put in a cummins combustion chamber.
If a product is junk then it is junk and mine were tested at my local machine shop,... as were the others.

You opened your mouth and proved the point by changing your own product you showed it was sub par and that's why you have attempted a re-do,... also yet to be proven. Why would you change it except that it was not cutting it. The proof is in your change. Your just lucky others haven't tested theres as I did or they would know. I didn't read about you giving refunds for your original springs?? Now guys know and will be getting their springs test and then they will know who is full of it!!

I didn't even use your name or product but you decided to come at me so suffer the result.

So your telling me that since a company went and modified their part to make it better then that automatically means the original part was junk? Damn. If everyone went by that then no one would ever develop a new part or enhance the design of a part. Technologies have changed over the years since Zach first came out with his springs and all he did was implement them into his new springs to give us an even better product.

And since you seem to have the spring rates of Zach's springs used and seem content with calling him out since he posted a rebuttal to you then why don't you post up the spring ratings? After all, if they are as bad as you say they are then the public needs to know.

Talk about logic??

So I buy something that proved after 20K it doesn't hold up and then I'm suppose to spend the time and money to have another set put on,.. now that's not logical.

I'm saying YOU knew before this for sure and that's why you changed them,.. duh!

All the proof you need is coming your way by other readers who will dang sure have their springs tested now and then the embarassment will be front and center.

And why would they believe me,.. at least enough to have them tested? Because unlike you I'm not selling them anything.

Exit left yourself.

So you expect us to believe you without any proof other than your say so? If I didn't know better I'd say that you were running someones springs, another company told you theirs were better from the testing they've done, sold you a set, and your just regurgitating what they told you.
