On that Hydraulic roller motor, I ran the cast iron 462 heads with Comp 1.50 roller rockers, the
short version of Crower poly locks, and the heads were easily cut for the Crower valve springs. They do fit under the finned aluminum Edelbrock covers very nicely, and also fit under the GM finned Z/28 covers but I did run the double-thick cork gaskets to get the right clearance. (gaskets can be seen in the pics below)
Such a great combo, and one of the biggest Hyd Roller profiles you will find. I'm sure those last 2 videos are a true testament to how well-mannered that cam really was at low speed, and how well it pulls up top. Made great vacuum for the power brakes and vacuum-powered headlights too.
Great Camshaft!
