Valves

[3W Hank]

Brian,
Just a thought.
I has been running in NHRA stock eliminator Mopars since the late 80's and back then it was a idea that valvesprings killed HP.
I was using the green MP springs, and if memory was correct I was using around 130 on seat. Idea was go as loose and no floating valves.
Years went on and soon that debate went into use way stiffer springs and I was way over 200 on seats.
On my old Hemi I used a cast std journal cam and used ceramic lifters and had around 250 on seats. Those intake valves was ca 130 grams.
Now I has a 60 mm tool polished profile steel cam and intake valves at under 100 grams a Trend tool steel lifters PPC coated.
Springs conical and is at 300 LBS on seat.
I use syntetic 0-20 oil and it rews near 9.000.
I don't call it 'stock' now but this is how far all this went, and its a 60K project.

Idea now is it not matter on HP how stiff the springs is as each take the other one off.
But ideas change in racing as years go on.
