I find myself low on presentable heads. Consider this page for reference only until I can have: 1) bad "gasket" surfaces milled smooth, 2) broken fins built up and shaped.

920 heads with five angle (75, 60, 46, 31, and 15 degrees) valve jobs with new stock size stainless steel valves with Stellite tips and faces, Viton valve guide seals, and fine wire springs (good to .560" valve lift). Ports lightly massaged (there is very little that can be done) for better flow.


No longer available: the mfg did not find my volume cost-effective.

The same as above with finer wire, higher chrome and silicon springs, titanium retainers, good to valve lifts up to .600". Titanium jumped a LOT in price recently.


The above assembled with a set of HARD rockers and flow-modified fittings and high quality drive-side bearings. Ports opened on the intake to accomodate large flanges (stock and Mikuni), and raised and polished on the exhaust.
