408 hyd roller, too much spring pressure?

No backpedaling at all. YOU are on a CHRYSLER site. Unless you specify you want to talk about stud mounted rockers the discussion is about shaft mounted rockers.

I must say there is a propensity for you Australians to pull this ****. Be offended if you want, but there are now four of you here who do the same **** all the time.

Stay on topic, or start another thread about beehives and stud mounted rockers. The sad thing is Chrysler stayed with shaft mounted rockers when the entire racing world said a stud was better. Now, all the Chevy guys run shaft rockers and Chrysler went to stud mounts.

Once again, Chrysler went backwards. There is NEVER a reason to use flexible stud mounted rockers.

Yes, this is a Chrysler website. And Magnum heads have . . . wait for it . . . But you made the blanket statement about geometry, not me.

US$64 for 8 valves (assume we're only swapping the intakes). The last set of Manley intake valves (x8) I bought cost around US$150 plus delivery and tax. The last set of heads I had re-lined and valve-cut with additional work to narrow the valve guides cost around US$450 – and that was considered a decent price.

You guys have no idea what we pay for parts and machining over here. Not to mention the OP, who lives in Sweden.

You appear to have a very narrow view of the world. And I'm not offended. In Australia, we tend to call it like it is. Which is all I have done.

Now, you go back to your gilded workshop with its exotic Ti valve gear and US$8 valves and I'll keep working on my cars with the resources I have. As I said earlier: horses for courses.
