Just wondering if anybody would know what the gap should measure in the two top coils when the spring is compressed. I'm not sure if i have enough or not. They look close but they are not touching.

Hmm, yea but should I have alot of gap between the coils with the cam I have or should they be mostly compressed?

you dont measure a conical spring like that, the coils are the top are weaker than the bottom coils

why do the bottom coils compress first?

Just measure installed height with the proper tool. 1.800 it is.

Upper coils are stiffer, lower coils collapse on top of each other taking out their effective mass for acceleration of the open valve. I wouldn't worry about it. As stated, check installed height, clearance to seal and amount of distance to coil bind. I think your original problems was the retainers or the springs and I wouldn't trust the Ebay vendor you got them from.

just adding... its the other way around, top coils compress first. beehive or conical springs are known as variable rate springs because the smaller diameter coils (top) compress first, then gradually as the installed height decreases, the bottom coils start to compress adding more pressure

sure hope so. I guess if ity does it again then it will get a dual setup. I do agree with ya about the first set of springs. I just wonder if they were fake or just crap

Incorrect with beehives

Incorrect as well.

It is actually the opposite

I was thinking that also.
