My 360 Six Pack build!!!

Yellow Rose, my valve train issues with 273 OEM Rockers and Crane Ductile were that they didn't have enough clearence between the rocker and the springs, so the spring retainer were hitting the rocker, I wasn't able to even bolt them. Aftermarket aluminum rocker have recesed clearence there and they fit. I move to beehive spring just to get a wider option of rocker for my setup.

Other thing that is know and I missed is when using mechanical flat tappet cams extra pushrod hole clearence is needed, i checked that at Hughes Engine web. I have done this now.

Now for the Rocker geometry, I did check the rocker travel on the valve tip with the Proform rocker and they were almost at center (a little bit to the shaft side) and along the cam lift they moved out (@0,50) and back to its position from @0,50 to total lift. Don't remember how long was the pattern on the valve stem top, but sure it was short!!! What am I missing?
