WTF? A small block has a cam retaining plate. It can’t move forward. A big block doesn’t. It relies on cam lobe taper to keep the cam centered in the block.

Going to a roller eliminates that taper and you have to keep the cam from moving forward in the block.

Sound familiar? Same thing on a cheap assed SBC.

Buy a Milodon gear drive and be done with all that junk. Buy once, cry once.

Has been brought up before wether the button is necessary or not. Many posts later the verdict seemed to be it was necessary. Seems to be a very small portion of people that go without.
The rollers do not have the shape of the lifter or cam lobe to to keep the cam from going forward.
I am going with the aluminum cover. If I do not go that route modification of the stock cover is not that big of a deal.
