.509 292 108 in 440

I must have had the luck of the simple minded then. I degreed the cam, installed straight up, ran the springs that were suggested my mother for the .509, checked installed height but they were all pretty close, and ran the tar out of that 383.
The 30 years since without a hot Mopar and constant research has made me more cagey. I appreciate the advise. I have limited resources and can't afford decent adjustable rockers, so if the preload is off (likely) then I will just have some pushrods cut. If the contact area of the rockers on the valves is off (slightly possible because of larger valves, but unlikely) then I will have to shim the rocker shafts. I have basically one shot, want to get the biggest bang for the buck without doing something stupid. I wI'll take all the advice I can get. Appreciate you guys and gals.
