ADA Racing Billet Cylinder Head Dome includes compression(OR042) and dome top(OR020) o-rings. Squish relief is .005 inch @ 82.5mm(fits up to 83mm piston) with a 4 degree angle. These domes fit the standard ADA Racing 750/800 Head and the original ADA Racing Girdled Head with the billet brackets. See Related Products below.

All compression readings are at sea level on a stock, non-ported cylinder. Every 1000ft increase in elevation decreases the compression by 5-7lbs.
