Notes: Designed for 1986-91 Tuned Port Injected (T.P.I) 5.7L small-block Chevy Corvette engines originally equipped with centerbolt valve covers. The intake bolt pattern utilizes the 1986-91 (straight) 90° angle on all bolts. Spark plugs are angled like stock O.E. heads. Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using.

CARB EO Number: D-215-94
