yes a good catch can is also a must, and just because you can run the stock balancer or a cheap aftermarket does not mean it will help the harmful vibrations that take its toll over time, there is a reason they make them and on a good old SBC/BBC the deal was the hydraulic cams usually are under .500 lift by far and not rollers with our much higher more radical lift and they were really harmonic balancers but not the best made as they were basically a weight made for the crank and the cheapo way to do elimination of harmful vibration is for a rubber layer between the pieces of metal joined together making up the harmonic balancer. I run a Fluidampr which actually has a fluid in it to help, ATI is another good one and I am just sharing this because even on a old school hot rod if you were really wanting to invest money that's a good place to put the money along with other things like Bushing rockers or better pedestals like the ones available from Livernois to help the rockers movement and that's one I am going to do with bushings eventually. Remember the thing is a deal to last the long term, the investment now may cause less money spent on the first spring change when you check over all the upper valve train for wear/bearings/ wear patterns/ damage /etc.

Our engines do have a lot of spring pressure for a cam, and I break in my cam with BR30 just like a engine even with a 8620 core, because you cant fix stupid. And a failure does not always happen right away, it comes many miles down the road, not like failing to break in flat tappet without enough ZDDP in the oil and failing to even break it in proper it will not fail within the initial break in of about 30 minutes at varying rpms. And it will not immediately round off the cam lobes sending all the metal it shaved off into the engine to trash every bearing and hurt everything..... And why smart old hot rodders know to break in a cam right, and not throw the baby out with the bath water as you only have yourself to blame if you could have done more or learned more to prevent using the wrong oil or the wrong part etc...... AS people who are into restoring cars and old hot rodders know you cannot trust even the oil now and for break in you need initial wear to seat piston rings, seals etc, but you have to keep it strong with ZDDP for the Curing of the cam....... then you can go more slippery but don't be too slippery you may drag rollers instead of them turning, etc, etc....Just stuff you learn over time.
