Thanks PRH for the confirmation on the retainers and locks. I am hoping for the same results on my retainer lock combo.
I ordered a valve height micrometer from Summit last night and will go back to work on this after Christmas.
I am wondering if Comp cams is discontinuing the 954 spring also. Like the Isky spring it would install closer to the OEM perimeters of the original springs, while also offering more spring pressure.
As brought up the springs seem to stick out pass the retainer and the comp cams retainer is slightly smaller diameter than the Edelbrock.
I have not played much with cylinder heads and even the 10 degree locks are new to me.
