W2 head installed valve spring height

I've been going through my old posts and updating them. I installed that Lunati cam, lifter, spring, kit in November of 2013. It's first hit at the track was the Thanksgiving race at Las Vegas. It was a disaster. It bent several pushrods and destroyed 2 rockers. I had checked for clearance with putty and found .200 inches + when I assembled the engine. I also degreed the cam. I didn't have spring bind, and was at a loss to explain what happened. I replaced the damaged parts and reinstalled the .557 Mopar cam and ran for about a year with no concern when I sucked an exhaust valve in number 8 cylinder. I found the springs were already worn out and had less than 90 lbs pressure, (so I'm not happy with Lunati) Luckily I had only damage to the #8 exhaust valve, it was stuck in the head and didn't damage the piston, (there's a tiny little scuff mark on the piston). I had the machine shop replace with Comp Cams springs. and redo the valves and guides on both heads. Reassembled and had no concern until I tore it down in 2019 for maintenance and upgrade. I freshened the engine and installed a Mopar 590 cam. Degreed the cam and checked for interference and spring bind. Looked really good, lots of clearance. The putty test showed .220 inches of valve clearance. I wasn't able to put I back into the car until February of 2020. After break in, best hit on the track recorded a best of 10.95 in a head wind in Phoenix with letting off the throttle. Went to Tucson (3150' track altitude) and ran a best of 11.14. With the Covid-19 restrictions haven't been able to race anymore.

I recently found 32 (brand new in the original boxes unopened!) discontinued P2946353 Mopar Performance valve springs which are supposed to be the bomb for W2 heads. They have the proper installed height and good spring pressure, (I'm taking them in to find the installed and over the nose pressures). My plan is to try the Lunati cam again with these springs and see what happens. I'll do all the clearance checks very closely for safe's sake. Most likely won't occur until next year. The Lunati cam spec's are: Intake Lift .597, exhaust .620 (with 1.5 ratio). duration at .050 = IN 263 degrees, EX 271 degrees. LSA = 106 degrees. Centerline is 100 (yes that's correct) degrees with a 6 degree advanced set up in the cam.

I welcome any comments!
