I remember Racer Brown. back in the late 60s he was also doing traveling HP seminars for Chrysler (mostly providing info on the RB (440) engines).

Yeah those push rods are fun to adjust aren't they. I built the 354 in the Plymouth at the same time as I did the 331 for the 37. I did the push rod adjustment on both engines at the same time. I don't know what felt worse after I was done my hands or my eyes.

As far the the tubes to replace the springs I think someone was offering them as a kit at one point. From a performance standpoint they might not be a bad idea but not so much from a serviceability standpoint.

The problem with them is if you have to replace a lifter, valve spring or valve seals, you end up having to remove the rocker shafts. That in and of itself is not a big deal EXCEPT the bolts that retain the the rocker shafts are the head bolts. Chances are once the head bolts are removed the gasket seal between the head and block will be broken necessitating removing the heads to replace the head gaskets.
