With me, it depends on the cam, and the valve size being used. I like to be @ 160 on the seat with  the cams I frequently use. I know, from the amount of heads I do, where I have to be for valve protrusion vs. installed height. Aggressive cams, 2.100" + valves = more pressure.

Matt, makes one wonder if he’s so smart why did he have you do his heads! I have you do mine cause you know a helluva more than I do!!!

Congrats my man! Still loving my 2017 cvo limited. Just had my 10k service couple of months ago, zero issues.

Good advice, Kojak.
I did just that - just brought home a new 2019 Ultra Limited (silver flux).
2014 SERK seems to "ate itself". Lower end issues.

The point of contention is some customer is questioning the seat pressure (he wanted it to be 150).
I don't know of a beehive spring that's 150# at 1.850ish.

Sorry for being snappy, but these people piss me off. 

PS: He didn't tell me that s--t until I finished them, (That's what really got me going)

The subject at hand was seat pressure. I understand what spring rate is, valve train weight, ramp speeds, (acceleration)  and so fourth. That wasn't my question (Larry answered it already). But thanks for enlightening us with your infinite wisdom.

Yes and it matters. What spring rate and pressures are required? It is not a single answer, one size fits all, despite adequate travel for the lift.

But that is just one number, what about the spring rate?
And doesn't the weight of the springs and valves matter and should be part if the decision?

what are you talking about? it's pretty easy to calculate the rate using two data points (open & closed).
