The roller rides on the cam lobe. I dont have a cutout cross sectional view but my guess is that they sit in the slot of the lifter about halfway up. Maybe they just sit underneath it and its thats simple. Not sure, what does it matter? The rods keep the lifters from falling plain and simple.

the "rod" sits underneath the lifters . . . holding them up. When you remove the cam plate on the front, you'll slide the rods down the oil ports.

Don't think that's possible. From the pic in post #13 there's a pic inside the cam "way" where you can clearly see that the lifters don't sit on the rods. I agree w/99blancoSS. Sitting in the groove half way up seems the most logical explanation. Do you guys think some 5/16" brake line would be easier to use then aluminum rods?

I've used this 3 times now, and I've never had a problem. If you're braking a wooden rod, then you're doing something wrong.

Once you have the rockers off, with the push rods removed, you can spin the crank over to "push" the lifters up. They'll actually hang in the lifter cups by themselves. The dowel rods are in there for a short period of time.

The lifters are roughly cylindrical in shape. However, the top and bottom are bigger around than the middle. Therefore, there is an edge between the bigger diameter at the top and the smaller diameter in the middle. That edge is what sits on the tools, which is what holds the lifters up.

soo, out of the three materials(aluminum, wooden, or brakeline) which works the best? I'm in the middle of my cam swap right now, and have some 5/16" aluminum rods, but am thinking of getting some brake line...

i used wood, but steel is fine. just be sure to ease it in and take out the pushrods, just made the lifters stay up in the trays. after you get he new cam in, tap down the lifters and they will fall on the cam. its interesting to see how well the trays keep the lifters. my 54k mile motor's trays held up all of the lifters.

Default 5/16 dowel

I used a 5/16 wooden dowel. Common sense tells you if your having problems. If you need to force the dowel in, then a lifter is not pushed up in the bucket.
