The lifter & pushrod being used makes that a multiple choice question...

I knew this was not going to be a simple question. The intake is on the motor
so I cannot tell anything about the lifters. The push rods ? What is there to see on them ?
I am going to put these 941- Comp springs on my early GN 1 heads. Installed height is 1.73. This is what is driving my question about open rate.
