Valve train “stuff” is kinda my thing. My 09 geometry was dead on the money. Obviously the variable is the guide plates. A factory setup with stock rockers is almost bulletproof. When you add roller rockers guide plates and 3/8 pushrods things get a little dicey.
My 09 has scorpion rockers (1.7 ratio) 5/16” pushrods and show cars guide plates. I indexed the screw in studs 8 degrees and 12 degrees and figured that 1.7 ratio rockers would be easier on the valve train. 135# seat pressure also helps...this is not a race car!
