"Has you revved it like that again under load and got the same thing? wondering if they took more than a skim on the heads and you needed shims under the rocker posts? did you check the lifter pre-load?"


Never noticed it before but I don't think I ever stood on it like that before. The shop only machined off a tiny amount, this guy is really good. You should see this cracked flathead Cadillac head he did a stich repair on. This guy's an artist. He spent $40k for his surface mill. I didn't check the preload as he only took off about 0.0020" and the heads looked like they had never been machined before so I felt I wouldn't likely exceed the tolerance. My guess is some of the grease and vasoline made it by the bypass in the filter and got to the lifters and then had a hard time flowing out. It's runny beautifully since then so I'm not worried
