keep your shorts on Grasshopper I had to get out of my pajamas and put my clothes on LOL it's quite a bit earlier here..
So back to testing the material did you Sonic test all the retainers and clips and everything? LOL I'm sure Fishman did, that's how he knows..

I'm afraid I'm old and I don't put absolutely everything you say and do in my permanent memory banks which like I said I'm old..
You could always swap over to some aluminum retainers if you're worried about failing! Hmm, aluminum retainers or these here Chinese retainers......which to choose
go some intake gaskets and main and head stud hardware, I ain't ever fiddled with these before IE. ARP, but I thought there would be more precision in the interaction of the 12 point cap screw and the stud, seems to wobble more than I would thought when screwed down on the stud to the top of the nut.

Spitballing but I wonder what happens with heat expansion..?..

Just got done talking to a friend who bought big block Pro Comp heads 10 years ago and had a valve failure with both the intake and exhaust in one cylinder at probably 7K at the big end of the track... (134mph) Took out his big block Stroker.. he put new valves in it when he rebuilt the motor and still has them to this day. Just isn't convinced the hardware was very good.. so I guess the question remains whether that was then or that's how it always will be..???..

Seriously you need that explain to you..
top of the line parts have failed too. If he was turning 7k, I could imagine the VS pressure....
Spitballing
When Jpar is so mad that spit comes out with his words
could be that a lock wasn't seated and let go. Bending/braking in the combustion chamber causing the other valve to get hung up knocking out the other keeper.
I had this problem with a stock head/eng that i installed shim under the valve spring,

My heads will probably get the blue color once-over and off to go...
I'm in your boat on this....

I'm just not sure if I should set the heads up with the old carbs and get everything in check, or the other way get the carbs set up and then pull the motor and do the heads..
won't matter, either way. It's not like it's a cam break-in....
But if you want to compare the heads against what you have, I'd do the heads first....
