Imo, it’s as easy as this........

You’ve done some research and are now aware that an old school build with retrofit hyd roller lifters can be pretty noisy in the valvetrain.
There are enough examples of it on the ole interweb to know that it’s not a fluke.

You just have to decide if you want to try it or not.
Nothing you read here or anywhere else is going to have any impact on whether or not your build will be noisy.

Case in point, Gaterman lifters. Nice and quiet in Andy’s build, yet I have a solid flat tappet cam on order to replace a hyd roller that’s too noisy for a customer that has tried Comp lifters and Gaterman lifters.
Interestingly, the two sets of lifters were noisy in different ways.
The Comps were real noisy at start up but got a little quieter after the engine was up to operating temp, while the Gatermans were quiet on start up but got progressively louder as the engine warmed up...... and were described as “quite noisy” with the engine at full operating temp......a lot louder at that point than the Comps.

DVW has a nice thing going with his 15 year old Cranes........ unfortunately those exact lifters are not available anymore.
They were built in house by Crane, but the equipment used to make them went elsewhere when Crane was sold.

We recently had a 446 on the dyno with a hyd roller and the Howard’s base hyd roller lifters, which are the “street” Morels.
Pretty quiet.........but..... made two pulls to 6100 and after the second pull some clattering was heard........one of them stuck/seized a plunger.
