So I already swapped out the drivers side of my 383 engine’s 915 heads and upgraded to my edelbrock performer rpm head. It’s all torqued down to spec and I can’t get the Harland Sharp rockers to fit all the way down on the edelbrock rocker pedestals. I took some photos of the problem. You can clearly see the gap between the rocker shaft and the pedestals. I keep comparing the setup on the edelbrock s as compared to the rockers on the passenger side 915 heads. I can’t figure out what I’m doing wrong? I should probably mention that the builder who built the engine and originally put the rockers on did carve out a lot of material on the underside of the rocker to get the rockers to clear the valve springs on the cast iron heads. I also took photos of the clearance between the Harland sharps and the springs on the edelbrock’s it does look like they are close to touching but maybe I could shim them somehow? Is it normal to have a little lateral play or movement on the rockers that sit on the shaft? When I look at the rockers on the iron head it has a little lateral movement on the shaft maybe 1/16 of an inch? I also took a photo of the difference in height of the pushrods sitting on the lifters which sit on the cam. Is this big difference in height normal due to the lift on the cam? I’m just trying to find out how to correct the fitment problem.
