Help with Valvesprings and valve float. Noob

I’ll repost what I said the first time around.
I encourage you to read the article in the link.
You can draw your own conclusions from there.


If the valvetrain is stable, as in........ lifters not doing things they’re not supposed to....... pulling clean well into the 6000 range is no problem.

Duane,

You won't get any argument from me that a solid has more rpm potential, but concerning the article you linked to, there is no mention of anything being done to correct rocker geometry. If the geometry is not corrected for each change in lift value, it will become unstable early.

Yes, more spring rate is required for higher velocities, but if the geometry is out in left field it will be much more than necessary. Because there is no mention of any correction, I have to assume there was none, and that makes the data less accurate. The OP may need more spring, but maybe he won't. Unless the geometry is correct, he won't know for sure.
