I went all COMP when retrofitting my BBC to a roller cam...

Cam
Lifters
Rockers
Retainers
Keepers
Springs


The heads were setup by a trusted machinist as per the cam specification and the rest was assembled by myself ( the valves were adjusted multiple times using various preloads )...

After a few thousand miles the noise of lifter clacking or tappets tapping has not diminished. Some research has enlightened me to the fact that COMP BBC retrofit roller lifters are going to be noisy and in many cases extremely so. I've not come across any notes of failures, just the noise.

I've now acquired a set of Howards 91161 lifters to replace my current COMP 854-16 roller lifters. Choosing the Howards lifters comes after a bunch of reading online about retrofit lifter noise issues and then just about quality of the currently available examples.

Be aware however that I've not installed these lifters yet. The tear down will begin soon though!
