Now I am second thinking this roller cam idea.
Do your homework now while it’s still easy to change directions.
Do a search for “hydraulic roller lifter noise”, there will be tons of hits.
Read through several threads on several different sites and you will discover that no brand of lifters is without dissatisfied users........ and that sometimes you’re still going to end up with something fairly noisy.
If after all that reading you still want to try the HR...... at least you’re doing so being better informed about the possible pitfalls.
