I called Texas speed where I got all the parts. They are leaning toward valve float due to not adjusting the spring installed height. I did just slap them in there.
I am going to pull a valve cover and see if I can get a measurement. They said I would likely need about .050 shim OR a .050 lock that drips the retainer. They happen to sell those. Might be an easy and cheap fix.

yes, shim the springs. .030 should fix it.

whoa, slowhawk checking in!
I did the lowering locks. they lowered the spring retainer .080 which seemed like it might be too much. I did some math and some measuring and should be .060 from bind at full lift. I called pac and they said .060 from bind is ideal. put them in, went for a spin and now it revs cleanly. I have some other limiters kicking in at about 7000rpm but it is closing the throttle and a nice smooth limiter. I will play with that tomorrow and see if I can get it to goto 7200. at 7000rpm it is still pulling hard. pretty sure that is still a little low.

Did the shims also fix the boost issue?

So, I had a .660 spring on when I bent a valve on mine. It was spinning the tires badly in roll racing at the Street Car Take over. I went to BTR .680 and then my guy that put them together shimmed them. I don't know how much but I never had an issue after that.

According to the post - he didn't install any shims...it was the .080 'lowered' locks that boosted the pressure.
It does the same thing as a .080 shim in other words...

spring height is a big thing with high boost. We run a 1.78" install height and no issue at 28 psi,7000rpm with reg BTR .660 springs.

Bump, did the locks change your install height and get you what you needed? I keep getting float issues above 6600 ever sense the cam was new and has less than 2k miles on it, if easy enough ill change the locks to help with installed spring height, to my knowledge there are 2 retainer designs, the more bell shaped and the flat ones, I have the older flat ones.
