I found an automotive machine shop that was recommended to me that would clean the head, pressure test it, and resurface it for $75. It's very tempting instead of sitting here all weekend trying to get it perfectly clean. I'm thinking the resurfacing might be a good idea anyways-- just to be sure because I don't know what kind of heat this thing may have been subjected to. CouldÆve been under a lot of heat and that may be what destroyed the cam before I got it. Taking a little bit of material off shouldnÆt have an effect on the timing chain or anything. What is an acceptable amount for cleanup: 0.020ö (0.5mm)? IÆm an engineer in manufacturing and 0.5mm is a lot to me! <img src="/forums/images/graemlins/baby.gif" alt="" />

Lemme think what you knowà I mean, uhà Let me know what you think.
