So I just got done putting in patriot gold dual springs on my X1 cam 97000 mile car......
is the spring pressure too high on the patriot duals for my lifters?

I put an Idle up to temp heat cycle on them.....
decided that heat cylce #2 was going to be highway driving... below 2000 rpm's on my way out to the Girlfriends house.....
so I started driving...and about 15miles into it ( 65mph 6th gear 1500ish rpm's) I hear this ticking...that is getting louder...and now is a clacking sound...
cant seem to localize it.....looked under the valve covers and didn't see any broken springs..... and I dont thinkl it is loud enough to be a spun bearing...from what I understand that sounds like the motor is coming apart when that happens.....and my noise is just a clacking that speeds up with rpm's

check and make sure your rocker bolts are tight, also might wanna check and see if you have a bent pushrod, if they both are good a collapsed lifter is always a possibility

I have hardened pushrods...and my car was silent before the spring change
rocker bolts are tight... double checked them when I pulled the valve covers to check to see if it was a broken spring

Well 97K is a lot so that could be possible. Try to Isolate which side.
What kind of rockers do you have?

harland sharp rockers... they are tight.....

How much did you torq them?

But did you check if the harlands were hitting the retainers. I've read a couple of threads when they made contact on spring retainers that are slightly larger than stock.

I had the same problem with the man. Threw a lifter in the oil pan.
