Speedmaster heads revisited.

Ok small update before I get suited up to start grinding. Customer needed spring heights so he could order springs. Number to left is the actual number with zero shims so I minus .060 for the minimum hardened shim I use. I usually prefer more when possible. Just got the heck of it I measured the valves as I figured they had to be different lengths because of the different shim packs I posted about earlier. Now this is the first and only set of heads I’ve ever ordered complete and they were set up for a .600 hydraulic roller cam. I really impressed by the looks of the 10 degree retainers and keepers. Way nicer than the 7 degree crap on Edelbrock heads that I throw in the trash bin. Now here’s the craziness in the next post.
