Great! Thanks for the info. I broke a rocker stud(comp) on #5 intake and bent both pushrods on that cylinder so Im upgrading the whole valvetrain to 7/16 hardware. Hopefully nothing else is damaged.
I got
ARP studs
Pro Mags
Trick flow guideplates
Trick flow pushrods
and ARP polylocks, but I can send those back now.
Thanks for input.

Got some pics today of the damage. Exhaust rocker stud on #5 broke. The cylinder pressure in that cylinder became too high since the exhaust wasnt getting out,the pushrod on the intake side and bent.
However I think the root cause is that the poly lock wasnt catching enough treads to hold it down properly. Also the poly locks I was using were a bit too wide for the rocker causing them to rub. Also the top of the poly lock was hitting the rocker body. All my fault I guess I should of checked it better when I assembled it. It ran fine for about 8 months though, I had installed 918 springs, comp studs and poly locks.

Well, I got it all together a few weeks ago and have put about 1k miles on it since. It runs great, and most of all I love how quiet the valvetrain is now, sounds stock.
Those trick flow guide plates fit perfect, I only had a bit of trouble lining up #1 and #2. After everything was tightened up I let it run with the valve covers off till it warmed up. Then the pushrods on those cylinders started squealing from rubbing against the guide plates. I repositioned them, and its run great since.
