Technical Notes: For headers, contact TTI (951) 371-4878. Offset intake rockers required, exhaust side accepts standard-spec rockers. May require additional pushrod hole clearancing for some combinations. Bare heads will have valve guides & seats installed, but will require final sizing and a valve job to match the valves you will be using. These heads require the use of a 14mm x 3/4" reach, flat gasket spark plug with a heat range appropriate to your application. |
