quote:I guess I need to know if the tube bump should be even with the block surface
I just went out and looked at two of my Cleveland blocks.
The hole where the tube enters is drilled oversized (to the tube O.D. itself) to about 1/4" below the pad surface. That hole is chamfered at the top.
So, the tube bump would sit on that lower hole surface, about 1/4" below the pad.
