My '58-'62 235 engine had a couple of hydraulic lifters go bad. So I pulled the side cover and discovered that I have two types of lifters in there.

I have 10 of the one on the left and two of the style on the right. I found replacement lifters on ebay and they look like the style on the right, not the left. The one on the left also does not have a hole in the push-rod seat of the lifter. Which style is correct??
